My last period started on the 14th of December and I had unprotected intercourse on the 19th of December. Is there a possibility I could be pregnant? My shortest cycle is 28 days, longest 29 days. Thanks.
If your periods are regular, you were fertile on December 26 to 30, 2016. You were not ovulating on December 19, so you’re not pregnant.
Hello I started my period on 11/27/2015. It lasted for 5 days. I did not have a cycle at all in December. Then 01/01/2016 at 5:45pm it started. It lasted for four days but not heavy. Can I be pregnant? Additionally, I’ve been feeling cramping periodically in the lower abdomen but felt no cramping during cycle.
My period started on the 6th of January and stopped on the 9th. When will I ovulate? Thanks.
With a regular 28 to 30 days cycle, ovulation typically occurs on the 13th – 16th day. The ovulation signs include changes in body temperature, cervical mucus and hormone levels. Pain in the ovaries may also be experienced.
Hi. I have my period on 21 December, my next period is on the 15 January but I am sick, sore and heavy breast, little pains under my stomach, watering mouth and a cold. Could I be pregnant? We have been trying to get pregnant for 2 years.
It is possible that you’re experiencing PMS. Wait to see if you’ll miss your period. Take a pregnancy test at least one week after if you miss your period.
My last period came December 5, 2015 until December 8, 2015. Supposed to had my period on December 28, 2015 I’m nine days late. Moody with lower stomach cramps from 30 to 45 seconds. Do you think I should take a pregnancy test or wait on my period.
Yes, you can take the pregnancy test now.
Hi Steffy, I had my last period on 15/12/2015. After that, I have been having unprotected sex with my boyfriend from 24 until 31 December. I did a PT (results were negative) on January/04 this year, I’m to do another one in 2 weeks time. I haven’t seen my period this month. Lately, there has been vaginal cramping and backache pains radiating to the waist, nausea and vomiting, tiredness, constipation and swollen breasts. Should I be worried that much or am I just overreacting?
When is your period due? The symptoms may or may not be due to PMS or a pregnancy; the symptoms are similar at times. You need to ensure that you’re testing at the right time as well. You can get the most accurate result if you wait at least one week after missing your period. In addition, the result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time. If you have tested at the right time and you’re not pregnant then you need to have your symptoms assessed by your doctor.
Ok, so my last period was Dec. 22nd and I was on the pill til Jan. 3rd which was when my hubby and I did the Baby Dance. I haven’t taken my pills since then and today, Jan. 7th, I’m spotting. My next menstrual cycle isn’t until the 19th. Any thoughts?
Since you just came off the pill, you may not conceive that quickly. Keep trying to conceive; give it some time. Good luck!
Hey, I had my period on November 27th n then no period for December as of right now I’m 13 days late. Could I be pregnant?
My last period came on the 10th of December and finished the 15 and me and my bf had unprotected sex from that until the 26. My next period was expected to come on the 7th of January. Am I pregnant?
Hi . I have my period on the 22 of November and had unprotected sex and it’s January 7 and I have not seen my period since. Is it too early for me to do a pregnancy test?
You can get the most accurate result if you wait at least one week after missing your period. In addition, the result might be even more accurate if the test is done first thing in the morning as the urine is far more concentrated at this time.
This is the time to do it; HPT in the a.m for accurate results!
I saw my period on 10 Dec and I had a lot of unprotected sex with my husband and today is 7 January. I was supposed to see my period but no sign of them. Do you think I might be pregnant?
The most accurate way to confirm if you’re pregnant is to take a pregnancy test at least one week after missing your period. In addition, the result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time.
Hey, I started my period on the 8th of December 2015. It is now January 7th 2016 I’m cramping little like I’m on it but no blood yet! Should I be worried?
No, you should not be. Since this is your second period it may take some time for it to have a set routine.
Hi, my boyfriend and I are trying to conceive but haven’t had any luck in doing so. We regularly have unprotected sex around ovulation time as well as when I’m not ovulating. My cycle is 24-25 days. From my last period on the 11th of December I have been feeling kinda off, light cramping every few days, sinus migraines two days in a row, back pain, hungry but then a little nauseous but I never throw up. I also have experienced light-handedness and feeling tired.I expected my period on the 6th of January 2016 and it came, but it seems kinda lighter than normal. It is only thin strip of blood on the pad. I have not tested lately for pregnancy and starting to lose hope that I will actually get pregnant. I had a miscarriage about five years ago as well. Can you help me?

I had my period on 30 November to 5th December, had unprotected sex on 27th December 2015 now I haven’t had my period. Am I pregnant?
Your chances of being pregnant depend on whether you were fertile on or around the date that you had sex. The number of days in your menstrual cycle is also needed in order to respond accurately.
My last period was on the 18th of december 2015,I had sex on the 21th, 25th and 28th of december. please am I supposed to be pregnant because my cycle is usually 25 days or 27 days long. Thank you
Hi, Once you have unprotected sex you stand a chance to get pregnant,try taking a pregnancy test.
