I had sex around middle January. I had my period on Feb 5. I'm almost sure it was a real period. Then I had sex with my boyfriend in the middle of February.. I then missed my next period beginning of march. Is there ANY POSSIBILITY I'm pregnant for the first guy? I had an ultrasound and I'm 14 Weeks... Which would make me pregnant for my boyfriend. But I'm still worried to death that I'm pregnant for the first guy. Help :(

If you had a recent ultrasound that put you at 14 weeks the baby would be from your boyfriend. If you had become pregnant about mid January, you would be several weeks further along. That would be enough of a difference to notice on an ultrasound.

Conceptions dates are not exact, but they are give or take normally only a couple of weeks,

So yes, you can ask and discuss this with your doctor to be sure, it it seems it should be your boyfriend.

I am sorry but maybe and should is the best you can get, to be 100 percent sure you can get a DNA test when the child is born, but I am fairly sure it is boyfriend

According to my LMP I'm 14 Weeks and 5 days. The ultrasound says I'm 15 Weeks! So I'm confused ): I had sex with a guy in January cause me and my boyfriend broke up.. I got my period on Feb 5. And me and my boyfriend had sex after and now I'm pregnant. I'm really stressing that it might not be my bfs baby. It just seems so good to be true... Is there any chance I got pregnant in mid Jan? I hear implantation bleeding can be as heavy as a real period...

I'm sorry to say but you can only asses paternity AFTER the birth with a DNA test of all the potential fathers.

The 14.5 and the 15 seem to be fairly near each other in agreement.

But yes it can be implantation bleeding and sometimes some women just have a period on the first month.

So you will just have to get a DNA test when the child is born to be sure.

When did you have the ultrasound that showed you to be 15 weeks? If you had become pregnant mid-January, you would be about 19 weeks pregnant at this point.

What was your LMP and when is your due date?

Well I had my period February 5. I had sex before then but thought I wasn't pregnant because my period. Then after my period I had sex with my now boyfriend. Missed the following period in march. The doctors say my ultrasound matches up to the lmp but I don't know my baby is a tad bit bigger than average so I'm worried. Like 16 Weeks the average was 4.5 inches but my baby was 5 inches.. At 21 Weeks he was 15 oz. but average weight at this point is 12 oz. :(helllppp

It is possible to have the first period ( but often lighter and shorter) but yes it is possible to have a the first period while pregnant.

So it sounds like you may need a DNA test to make sure when the child is born.

It is very possible to have break through bleeding during pregnancy. Some women experience it their entire pregnancy and mistake it for a period.

If you're at all unsure then have a paternity test done once the baby is born. That's the only way you will know for sure. The size of the baby can't really help you as every baby is different. Some are smaller than others, and some are bigger.

So I had sex in January then had my period Feb 5. Then had sex mid February and had very light spotting in early march. The doctor says that I conceived in Feb but my baby is slightly larger than average... I'm scared it's the first guys baby. My baby is 3 oz. heavier than average and half an inch longer... Help

THen you are going to have to wait until its born and do a DNA test... the best medical estimate on its conception date is plus or minus 2 weeks from their best guess... that means you have an entire month it could have happened... and anyone you had sex with in that month are daddy candidates.

I had one at 10 Weeks how far off can this be. I told the ultrasound lady I should be 10 Weeks cause of my lmp. Could it be two Weeks or more off? I had sex with a different guy before my lmp and then after my lmp with my boyfriend.

Your OB-GYNs estimate of the due date and thus the conception date is only accurate to plus or minus 2 weeks... meaning you have a 4 week window... and that's as good a guess as current medicine can make.

You are going to have to get DNA testing done to know for sure.

Please don't judge me or be rude I wasn't with my boyfriend when this happened. Well my boyfriend and I have had unprotected sex quite a few times. We broke up, I had sex with another guy in January. I had my period Feb 5 then me and my boyfriend got back together and had sex and I had light spotting and turned up pregnant. I got a hcg blood test on how far along I was, and a couple ultrasounds.. The doctors say I'm 22 Weeks because of my lmp in February.. So that would make it my boyfriends. I'm scared because we have already had unprotected sex and I didn't get pregnant before. Can the ultrasounds and blood work be a few Weeks off!

Please stop opening new threads on the same issue.

I will sum this up for you, there is no way to know who the father is at this point. While it may be the boyfriend, it is very possible to be the other person.

You will have to just get a DNA test at the time of birth,
