Introduction
A healthy menstrual cycle is essential for the reproductive health of women. Most women have regular periods which aids them in keeping track of hormonal changes in the body.
But in some cases, your period can get off track by days which indicates some underlying change in the body. Keep reading to know more about late periods.
What are the causes of a late period?
Although a late period can cause significant anxiety in women, it is most often associated with no serious underlying diseases. The cause of a late period include:
Extremes of reproductive age
With the onset of menarche, the first few menstrual cycles are unpredictable, irregular, and sometimes painful. This should not cause any health concerns in teenagers if their periods are ‘missed’ or late by some days.
As the age advances, the monthly cycle becomes regular as the body adapts to hormonal changes.
In a similar manner, the perimenopausal age is also associated with irregular, ‘missed’, or late periods. As the antral follicle count (ovarian reserve of eggs) decreases, the ovarian production of hormones and the feedback control on menstrual cycle disrupts.
The decreasing estrogen levels in the body cause a myriad of symptoms, hot flushes, vaginal dryness, insomnia, menstrual irregularities, to name but a few.
Pregnancy
In the anticipation of pregnancy, a late period can overwhelm you with happiness or immense anxiety if you’re not expecting one. Pregnancy is one of the most common causes of no bleeding on due dates.
But you’ll have to wait a little longer and get a pregnancy test to confirm it. Urine stick tests become positive as early as the first day of a missed period in women with a regular cycle.
Lifestyle changes
Certain lifestyle modifications can throw off the normal menstrual cycle:
Exercise
Heavy exercise can cause a missed menstrual period or cause them to stop altogether. This can often happen to women who are not physically active for a long period of time and abruptly starting a vigorous exercise or workout.
Menstrual irregularities are common in athletic women and are of no serious concern.
Exercise is not directly linked to the period cessation but is a stimulus of energy misbalance in the body. Heavy exercise leads to an increased gap in energy demand and supply which culminates as less energy available for other bodily processes and can thus delay or completely halt the menstrual cycle.
This, in the long-term, can severely impact the health and reproductive life of women, contributing to infertility.
Stress
Psychological stress can also affect the reproductive cycle of women and can result in delayed or missed periods.
Hypothalamus is the central regulator of almost all bodily functions. Chronic stress can tip the feedback mechanisms of reproductive hormones resulting in menstrual irregularities
Obesity and Weight loss
The excess fat stored in the adipose tissue ramps up the production of estrogen in the body. The increasing circulating levels of estrogen in obese women are mainly responsible for delayed or irregular periods.
Weight reduction is the first piece of advice given to women with abnormal menstrual cycles.
Contrary to this, women who are thin, lean, taking a low-calorie diet, fasting, or are exercising heavily to lose weight also suffer from irregular and delayed periods.
A healthy diet is essential for the normal functioning of the reproductive cycle.
Polycystic Ovarian Syndrome (PCOS)
PCOS is a gynecological condition in which the hormonal imbalance affects the overall health of a woman. The excess estrogen production by the cystic ovaries is the hallmark of PCOS.
This excess estrogen makes it difficult for the ovaries to release eggs, as they would do every month, to keep up with a healthy menstrual cycle. This leads to menstrual irregularities along with a list of other signs and symptoms.
Chronic Diseases
The diseases that run a long course also affect the menstrual cycle. Diabetes, Fibroids, Pelvic inflammatory disease (PID), Celiac disease, Von Willebrand disease, and malignancies are a few most notable chronic diseases that can cause menstrual irregularities.
Both type 1 and 2 diabetes mellitus can produce hormonal disturbances with disrupted blood sugar levels. Thus, poorly controlled diabetes mellitus can lead to late periods.
Pelvic Inflammatory disease (PID) involves the inflammation of reproductive organs that can also lead to menstrual irregularities.
Celiac disease is an inflammatory bowel disease that is exaggerated with gluten intake and disrupts the villus architecture of the intestine. This leads to impaired intestinal absorption of nutrients which contributes to late or missed periods.
Malignancies can induce a cachexic change in the body. Cachexia is the excessive loss of weight in cancer patients due to high cell turnover consuming a lot of body energy and speeding up the catabolism.
Decreased body energy levels lead to delayed periods or amenorrhea in some cases.
Thyroid Problems
Thyroid hormones drive the body’s metabolic process and maintain homeostasis. Both hyper- and hypothyroidism can cause late or missed periods.
The other symptoms of thyroid diseases are usually present long before the menstrual irregularities and reproductive dysfunction. Most of the cases resolve with treatment.
Birth Control methods
Hormones containing contraceptives downregulate the body production of reproductive hormones and thus changes in the menstrual cycle are observed on starting and stopping such birth control methods.
It may take up to 6 months for women to start bleeding regularly after stopping the hormonal contraception. Changes in the menstrual cycle are also observed with injectable and implanted contraceptive devices.
How to remedy the late period?
The management of late periods depends on the root cause. Nothing needs to be done in teenagers going through the first few reproductive cycles as their monthly cycles would become regular with time.
Avoid stressing your body with heavy workouts if you’re having menstrual problems. Stay hydrated and energetic to keep your body in balance.
Mental stress should also be avoided. Maintaining good sleep and limiting caffeine intake can help overcome insomnia that can help cope with stress.
Healthy body weight is essential to homeostasis of hormones in the body. Losing excessive weight gradually can restore the hormonal balance in the body and remedy the abnormal menstrual cycles.
Likewise, nourishing the body with healthy nutrients and fulfilling the daily calorie requirement is essential to avoid the energy-deprived state in the body.
For chronic diseases, such as PCOS, thyroid disorder, malignancies, etc., consult your doctor for prompt diagnosis and initiation of treatment. Menstrual irregularities often resolve after the treatment of underlying pathology.
Women using contraceptive methods often face abnormal uterine bleeding. Consult your OB-GYN if you’re facing menstrual irregularities with your contraception method.

I completely missed my cycle for July, also my cycle for August was suppost to start 3 days ago. is there a chance of pregnancy? should I take another test? or am I facing another reason for missed cycles?
Hello Nikki, There are tons of reasons for a missed period like stress,Premature Menopause,A Thyroid Irregularity and many more,check with your doctor.
My last period was june 22,2015, I’m a regular 4 my monthly period. But 1 year ago i got my miscarriage. Is this still affecting on my monthly period?
Hi There, are you having Irregular periods? you should probably check with your doctor to see whats wrong.
Hi, I’m 9 days late past my due date of my period. It was supposed to be due for July 27 and I have had a period on June 27 and I’m now wondering if there is a possibility of me being pregnant? Especially, since I am having a little cramping, but no other signs of my period. Every since the last day of my last period I’ve been having sex with my boyfriend about every other day and my periods usually last for five days.
Hi Trina, have you taken a pregnancy test as yet? if not you should because it is possible for you to be pregnant.
I last saw my period 2-6 of july and I has sex on 14 I have not seen my period.
My last period came about 10 days late. 13 days after it ended (which is the time my period was supposed to come had it not been late in the first place) I noticed I was slightly bleeding and it felt like my period but this only lasted one day. The next day I was spotting but this never happens so I’m just confused and wondering why this could be and if it’s normal?
Hello riri. I am not sure if I am understanding your situation you described. Also, I do not have enough info to determine what the cause may be. I would recommend you speak with a doctor or professional as soon as possible.
Hi, my period was June 21 – 26 2015 (36-37 days cycle). I had unprotected sex July 14 and until now my period hasn’t come. Is it delayed or am I pregnant?
It is possible you are pregnant. Your fertile days were July 10th-15th making your chances of conceiving very high. I would recommend you take a pregnancy test soon.
I’m 26 yrs old and married since early this year, my last period was 27th of June. I had sex with my husband several times in June, but I haven’t seen my menstruation and today is 29th but am feeling some pains on my breast and I’m feeling weak.
similar story got mine last June 27 haven’t seen it yet it’s August 4 … Unsure what’s wrong
My last period was on 18 June 2015 and I had unprotected sex on the 4th of July 2015 but he pulled out and never released inside me. I still have not seen my period since now, could I be pregnant?
It is possible that your period is just delayed. It is also possible that though he did not ejaculate in you, sperms could have been released in his pre-ejaculation fluid. In any case, it’s best to wait at least another week before you try a pregnancy test.
I saw my period on 13th June 2015, I had sex with my boyfriend on 20th June and now I still haven’t seen my period. Does it mean that am pregnant?
This depends on whether you were ovulating at the time you had sex. If you have a 28 days cycle, you were fertile from June 25 to 29; your fertile days depends on the length of your cycle. You must take a pregnancy test for confirmation. Remember also that your period may also be late for different reasons, take a look at this post http://womanjunction.com/8-mess-period/
Good day. My last period was June 19 and we’ve been having sex almost every day. Do I run the risk of getting pregnant? When they say everyday sex can reduce the power of semen, is this correct? Please reply.
Yes, you are still at risk of becoming pregnant. Although frequent ejaculations can reduce sperm count it does not mean that your partner cannot impregnate you. Once you have unprotected sex and your body is fertile, you can become pregnant. If your partner has issues with his sperm count then the chances of becoming pregnant would be low.
Hi my last period was June 21st 2015 and I had unprotected sex with my boyfriend on 26th June 2015 and 29th June 2015 and 30th June 2015 and the 8th July 2015 and the 9th July is there a chance I could be pregnant someone give me some answers
Hey guys I am 22 years of age. my last period started on the 30th of may had sex several times in the interval even on my most fertile days now its the 7th of July no sign of period but yet when I do the test they are negative. I have some cramps and sore breast. Am I pregnant or not
Hello Lucious. It sounds like you may be pregnant. Though, I would recommend you see a doctor, preferably an OB.
I’m confused! My period is always on time,and never abnormal. My last cycle was may 18 and it was a normal 4 days…my cycle is 28-29 days. I had unprotected sex on the 27….on June 2 I started to bleed not heavy and not the same color as normal. The next day I had a few small clots ..then it stopped . Had unprotected sex again on June 12. Still no period. . Help!
I would definitely see a doctor about this. I doubt anything is wrong, but it definitely seems abnormal and too complicated for anyone with no medical background to give you a solid answer on. Hope all is well!
Okay so my last period was April 26th and it was my normal five days. My cycle is 34 days apart so my next one should have been May 31st and today is June 4th and still no sign of my period. I’m almost a week late! My lower stomach hurts for a few minutes then stops and comes back. I’m always exhausted. Cramps but no blood. Tested but negative. I’m worried. I’m 26years
Hi there. Your next period was due on May 30th. You didn’t say when you had unprotected sex but if it was around the 14th to the 18th of May, you could be pregnant since those were your most fertile days so if you haven’t seen it by now, take a test and see your doctor to confirm.
I’m 25 years old, officially married for 5 months. My last period – 1st day was the 13th of April… (28 days cycle)… I suppose today is my 1st day of period for may but it still haven’t come. I’m checking a home pregnancy test but it is negative. Please advice me when I should take the pregnancy test?

I’m 29 years old , officially married for 8 months, my last period , 1st day was 17th April… and 28 days cycle… suppose today is my 1st day of period for may but it still haven’t come, I’m so excited to get a test, pls advice me when should i take the pregnancy test?
Hi,
congratulations for your wedding ! The best moment to test yourself is with the first morning urine, the HCG hormone will be then more concentrated so easier to detect if there is !
Good luck
