My girlfriend had her last period 10 FEB 2016 and was supposed to have the following one on the 9th of March 2016. We had sex on 8th March and pretty sure – 200 % i did let anything inside. Now she’s delayed 12 days and we tried 3 tests that were negative.
She had a cesarian last year September 2015 and also suffered UTI…Can you help on that ?
You have to ensure that the test is taken at the right time. 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.
Hi. Your most fertile days would have been March 7-12. Having unprotected sex can always result in pregnancy. If you are concerned you should take another test and talk to your doctor. Best wishes.
I saw my period on the 3rd of March 2016, and I made love to my Hubby on the 13th, 14th, 18th and 19th of March. Is there any chance of me getting pregnant within those days
This depends on whether you were ovulating or fertile during those days.
I had unprotected sex with my boyfriend on February 25. My period came on the next day and lasted 3-4 days. Had unprotected sex on March 7, 11,16 & 20th. My cycle is 28 days. What are the chances of me being pregnant? Really need to know ASAP!!!!
You were fertile from March 9 to 14 so it;s possible that you conceived.
I had my period around the 10th of Dec 2015 and finished it around the 14 Dec 2015. I Had sex with my ex on the 19th of Dec. I took a morning after pill on the third day but not too sure can’t remember exactly. I had sex with my current BF and had what looked like a period around the 5/6 Jan 2016 and I found out that I’m pregnant on the 7 Feb 2016. I’m 10 weeks and 6 days today. Could this be my ex’s baby or my current BF? Please help I’m going crazy.
It’s your ex’s baby sorry
I have the same problem as you. My bf and I had sex last August of 2015 and then I had my period for one day. After that, I had sex with another guy in October. I found out this Feb 26, 2016 that I’m 23 weeks and 6 days pregnant. Is it my bf baby or the other guy?? Please help me to find out.
Since you’re over 23 weeks pregnant then it is highly likely that you conceived for the other guy.
So it’s the other guy’s baby, right??
It is highly likely. Can you recall the date of your October and September periods?
My last period was september 13, 2015 and then on october I don’t have period and so on,,
Had my period february 17th. Still not here. I should probably test, right?
That depends. When you are a teen, cycles tend to be whacky, and not very reliable. You can have you period anywhere from two weeks before to two weeks after your supposed time, and have it not be a worry. Your cycke shoukd become regular as you mature, but if not, it wouldnt be a bad idea to get checked out. 😉
Wouldn’t hurt.
I had my period on the 14th of February, and I haven’t seen my period till now, am I pregnant
Me too. I’m taking a blood test tomorrow. My nerves are too bad to wait any longer.
Hi. I had my regular period Feb 12 and I had sex Feb 21. I got another period that was mild – not heavy and it lasted a few days longer. Can I be pregnant? I was scheduled to have my regular period on March 10 but it didn’t show.
I had withdrawal sex 4 times on the 1/2 of March. Last period was Feb 17th and lasted 5 days. I normally have a 28 days cycle. Should I be worried yet? I’ve had period pains on and off since the 9th.
Could I be pregnant? My last period started on the 28th of Feb and was done by the 3/4th of March. On the morning of the tenth I had severe cramping, which is usually a side effect when I ovulate on the right side as I have a cystic issue there and was prescribed a pain killer from the dr. to deal with the pain during ovulation; however I’m not sure if I actually ovulated that day or my body was just preparing, I was already having my ovulation pains and thought about canceling but my boyfriend and I ended up having unprotected sex that same night of March tenth, and again on March 13th. There was one additional act on the evening of the 16th. It’s been on my mind whether I could have gotten pregnant as I’m not on birth control, though I know the chances of actually conceiving are between 1/4-1/3, even given it being the perfect time. We’re not TTc but I’ve been noticing symptoms. Within days I was having severe headaches and feeling more hormonal than usual, and I wonder if these were really just ovulation symptoms. If I assume I ovulated on the 11th then I’m now 9dpo and have extremely extremely sore breasts which is not a common pms symptom for me, as my primary symptom is extreme moodiness, which I can’t say has been amplified. I’ve also been a bottomless pit the last week or so with extreme and random protein cravings (I’m a vegetarian so for me that has meant getting hard core cheese and fried tofu munchies) and getting breakouts on my face and body (maybe it’s the fried tofu! :P). Only very soon after having the sex did I have cramps but haven’t had significant ones since. Part of me is hopeful, but I also wonder if it’s all in my head. Please help!!
Hello there, yes they may be due to a pregnancy. I would suggest that you wait for your next period date and see if you get it or not. Also, the ovulation days are the ones where you have the highest chances to conceive, but it doesn’t mean that unprotected sex on any other day can’t result in pregnancy. Until you want to get pregnant, please always always use protection. All the best!
So I had my cycle on February 7 and I’ve been taking pregnancy tests which show negative but yet I haven’t gotten my cycle for March yet and I feel pregnant. I’m ALWAYS 21 days to each cycle and I was supposed to have my cycle on March 1 but I haven’t since February 7. So could I be pregnant and it’s not showed a positive result yet?? How much longer should I wait to test again to get a positive result??
If you were pregnant the results would show positive by now. Read our link on how to improve your chances of getting pregnant http://womanjunction.com/how-to-get-pregnant-guide/
I started my period on 4 March and finished on 8th March. My cycle is 30 days. When is my fertile date?
Hi. Your most fertile days would be March 17-22, April 16-21.
Hi my period date is always the 16th of every month but now i have missed it and it is now the 20th of march would i be pregnant ?

Hi. You are most fertile March 18-23. Good luck!
I have not had my period since January 30 and I have not gotten my period. I took a pregnancy test a week later in March but it was negative. Could I still be possibly pregnant?
Hi Zoe. You should contact your doctor.
Hello I have problems to calculate my cycle, my first day of my last period was 14-02-2016, and I had sex on 01, and 03 and 14 of March until now I haven’t get my period and I’m worried never been pregnant before, please help me do you think my period is late or??
Hi. Your most fertile days were March 12-17. It does seem that your period is late. Unprotected sex can always lead to pregnancy. You should take a pregnancy test and consult with your doctor if you are still concerned.
