I had a baby 7 months ago I just stopped breast feeding at 5 months I’m not using protection during sex just pull out method. I’ve been feeling weird not usual pregnancy symptoms just cramps in my group back ache. and nipple are really sore, lost of appetite and head aches. not sickness or anything but I did have a natural birth which put hectic on my body. so i’d like to know what this is. my husband’s worried, I already have an almost 3 year old. I’m freaked if I am but how could it be. while breast feeding my cycle hasn’t returned since birth. any chance I could be?
Hello. The risk of pregnancy is always present when you have unprotected sex. I understand that you may be nervous. You should take a pregnancy test and consult with your doctor about your symptoms.
Hi, I recently started taking birth control pills in January.I had a cycle in January on the twelfth and at the beginning of February on the fourth. The cycles were twenty-three days apart and lasted for seven days, pretty steady. I haven’t had a cycle since which concerns me. I was late a few times taking my pill and I had sex around February 19th and 20th, supposedly close to my ovulation days. Should I be concerned?
Since you did not take the pills as you should have, you might be at risk of becoming pregnant. Wait to see if your period will come. If it does not then you need to take a pregnancy test at least one week after that date.
I had my period the end of January. My tubes are tied, but I have yet to start my period. Should I think I’m pregnant?!
I had my last period on the 3rd to 6th of March and had unprotected sex from the 11th to 14th. Can I get pregnant? My cycle is 24 days.
Yes. You were ovulating at that time so the chances of getting pregnant would be high.
You are likely to be pregnant, because your most fertile period is March 11-15…please wait for another one week to test for pregnancy
My last period was 16 February 2016 when can I expect my next and when will be my fertile days.
My last period was 13th of feb normally 28 day cycle but still have no sign of March period but test says negative
Omg Toniee same here! My last period was Feb 13th as well and I’ve taken a pregnancy test yesterday which was negative! I’m always regular so this have me nervous. However, I’m spotting but still nothing. Any signs of March period for you yet?
Hi, have been so worried for a very long time, have never been pregnant all my life, and yet have never gone for any abortion. I am having issues in calculating my ovulation cycle, I seriously need your help thank you.
It is important for you to keep a record of your menstrual cycle on a calendar or on a smart phone; there are many ovulation apps available. The first day of your period should be counted as day 1.
Typically, the menstrual cycle will last for 28 days, which is calculated from day one of a menstrual period to day one of the next cycle. Ovulation typically occurs 14 days before the start of your menstrual period. If your cycle lasts for 28 days, you can ovulate on the 14th day like the average female. However, you will start ovulating around the 11th day if you have periods 25 days apart
I am 16 years old. It is March 14th and my last period was on December 22. I have had no signs of a period. No, I’m not pregnant, I have not had sex before. What could possibly be wrong?? I’m panicking!
Your period may be delayed because of hormonal or other reasons. Read our post via this link for more information http://womanjunction.com/8-mess-period/ You need to consult a doctor for an assessment to determine the actual reason why your period is late and you’re not pregnant.
At 16 my menstrual cycles skipped months and I was a virgin too…..so my mother took me to the doctor and I had cysts on my ovaries. Consult a doctor as soon as possible.
Is it possible to have sex on the fourth of September and give birth June 17th.
Yes, it is possible.
Hello, my last period was February 13-16th and it hasn’t come for March yet. Is it because February was a short month? I am still waiting. I took a pregnancy test that said I’m not prefab but I’m not sure if I did it right, (I forgot to put the cap back on after I urinated on the stick). Should I wait a few more days?
I have my menstrual 5th February. And I make love 21st February I see my menstrual on the 12th of this month and it last for one day, i don’t know what to do.
Hi am Steph,I had my period on 17 Dec till 22,always having 25days cycle but Had my Jan period on 13 lasted till 18,it returns to 25days cycle in Feb which I had 7-12 and March comes in 8-13,please what’s going on,am I having irregular periods this year I and my husband have been trying for a baby since last year.
Hi Steph, I would suggest that you calculate your ovulation day with cycle length as 22 days as your cycle is getting shorter sometimes. All the best!
I was supposed to have my period on March 7th..and now it’s March 13th and still have not had it. I’ve been having yellowish discharge and lower back pains, nose hurt, ear feels like water is in it. I took a test when I was 4 days late and it said negative…So I don’t know if I should just wait a couple of more days a take another one and see what happens?!?!
Take another test by March 18 for the most accurate results.
Hi. I had my period on the 16th of February when is my next period? December my period started on the 25th and January on the 20th.
If your cycle remains the same (26 to 27 days) then your period is due around March 12th to 13th.
Ovulation started late afternoon on the 26 of February had sex on the 28th. My period is usually lasting five days and is usually a 32 days cycle now today is day 37 no period as yet. Is it possible that I could get pregnant?
Yes, it is since ovulation typically lasts 4 days. Having sex just before and after ovulation can increase the risk of becoming pregnant.
