Hi, I got my period on December 31, 2015 and ended on January 5, 2016. I had been having intercourse. On the 13 of January through the 16 I had been feeling my uterus is sore I’m also bleeding could it be my period? Or why does my uterus feel sore and it hurts?
It could be your period. When is your January period due?
On January 26…I also would like to know why I can’t get pregnant; I have moré than 8 months trying, I’m not taking any control pills and I have íntercourse every other day.
I had my period on Dec 18, 2015 and it lasted my normal time. I have had unprotected sex every day almost since then with my fiancee. I was supposed to come on my period today Jan 15, 2016, no period, no symptoms of a period, slight – very slight cramping yesterday. Could I be pregnant or when should I test?
You can get the most accurate result if you wait at least one week after missing your period before you take a pregnancy test. It is even more accurate if it is done first in the morning as the urine is far more concentrated at this time.

Hi . I have a 28-day cycle and my last menstrual date was 15th December. I had unprotected sex with my husband from 26-1st January. Per my application I’m supposed to menstruate on 14th January but I bled for 3 days from 11-13th January. It’s the 15th and I’m not seeing blood again. Can I be pregnant? I have severe tummy aches.
Hi,If what you actually saw the 11-13th was your period then you are not pregnant but if the blood you saw was not like a normal period it could mean you are pregnant wait another week and take a pregnancy test to find out.
I had my last period on 14 Dec and still not had one. Had sex on 25 Dec when OPK was positive but HPT has been negative to date. Had sore boobs for last 4 days but not today. What do you think?
Hi my last period was December 2nd and I haven’t had one since then. What do I do? I don’t know when I ovulate because my periods are irregular and it is the 14 of January. I’m so confused.
I strongly believe you might be pregnant because my last period was Dec 5th I took a HPT Jan 6th and it was positive I also have irregular periods.
My last period was the 6th of December and lasted for 4 days. On the 21 of December, I was bleeding again just for that day and I had sex and now I’m unsure of when I’m supposed to get my period. And why did I bleed for another day when I already had my period?

I haven’t had sex in 3 years now but I have missed my period for 3 month could anything be wrong?
Yes, you need to visit you doctor for an assessment.
My last menses started on 29th November and ended on 6th December. I had sex on 3rd January and my menstruation is not back. Can it be possible that I’m pregnant?
Your chances of being pregnant depend on whether you were fertile on or around the date that you had sex. Can you confirm the number of days in your menstrual cycle? This information is needed to provide you with the most accurate response.
I had my last period in November around thanksgiving more like Nov 24 – 31 and haven’t seen my period again. I took a pregnancy test, it said negative now it’s Jan 14 and still no period… WHATS GOING ON?????? PLS HELP.
You can have missed periods without being pregnant. Read our blog post for more information http://womanjunction.com/8-mess-period/

My doctor said I conceived on the 25th of July. Is it possible that having sex on the 6th got me pregnant?
No, it is not possible that you got pregnant on July 6th. Your doctor is correct, you’re 26 weeks pregnant.

Hello, It would be hard to tell the exact time you conceived but you can get the closest possible date which would be the 19th and 21st day hope this helps.
My period are always regular, and always 28-29 days apart. Lasting 4 days…
My last 3 periods were:
10/15/15
11/13/15
12/11/15
January is a no show. It was supposed to come 01/9/16
Me and my husband did have unprotected sex for about one week and a half… I should’ve tracked when I was fertile, we had sex on all my fertile days.
I have been feeling some symptoms now that you look back and think about it more.
My last period was on December 14 and I had sex on Jan 10. Can there be a chance of me getting pregnant?
Your chances of being pregnant depend on whether you were fertile on or around the date that you had sex. Can you confirm the number of days in your menstrual cycle? This information is needed to provide you with the most accurate response.
