this is crazy and I regret it so much, but...

Finding out an exact conception date is hard to do. If you are certain that he did not ejaculate in you then the chances of him being the father are slightly lower then your boyfriend. However you are going to have to tell them both that one of the two will be a daddy in the next 7-9 months. I wouldn't wait to long to share with your boyfriend that you cheated on him and that he may or may not be a daddy. Sorry buy I can't respect a girl that allows herself to make that kind of choice just because she is mad at her boyfriend. It's life we all get mad at our boyfriends/spouses at some point. Do we run out and cheat? Nope pretty sure the majority of us do not. And drinking has nothing to do with the issue at hand. You were mad at him, the drinking part just helps you with your excuse as to why you slept with someone else.

Don't listen to negative judgemental people. This woman came on here for an answer to a question, not ONE persons personal opinion. No one is perfect an people make mistakes. This is a difficult situation to be going through. Because you didn't have a menstruation seperating the partners its difficult to say for sure who is the father. With that being said, have you had an ultrasound yet? If not, you should call and schedule one as soon as possible. Ultrasounds up to 8 weeks can tell you with accuracy to within a few days. To figure out a conception window, you would need to know how long your menstruation is monthly and if it is regular and consistant. You can google a conception calculator.

How long is your average menstrual cycle? If your last period was Nov. 25, you would have to have a menstrual cycle of minimum of 35 days in order for it to possibly be your ex. Women generally ovulate 14 days prior to their period coming (that's what triggers your period).

If you are on a normal 28 day cycle (which most women are not) that would put you at ovulating on Dec. 8. If you have a 30 day cycle that would put it at Dec. 10. Etc. You MOST likely got pregnant from having sex on Dec. 10 or even Dec. 4. Sperm can live in the body for up to 5 days (though there is debate over whether or not they can cause conception for that amount of time) and you can conceive for a day (possibly two, but most sources say 24 hours) after you ovulate.

Hope that helps.

I found out I was pregnant early December 2011. I slept with my ex on the 15th October and got my period on the 18th. I then slept with my on off partner on the 30th October for about 2 weeks. My periods are always irregular. I had an ultrasound on the 24th Jan and they gave me a due date of the 2nd August 2012. Is it possible the 1st guy is the father as I got my period only a few days after sleeping with him...please help???

No, it's not possible that it's your ex. I'm sorry. You got pregnant during the first half of November. Likely between November 5 and November 11.

There is no way to know I'm pretty sure. Unfortunately you are going to have to wait until after the baby is born to figure this one out. The best thing to do is to talk to a doctor in these situations, they can give you the facts in a non-judgmental and confidential way and help you make informed decisions.

That's not true. Using a conception calculator based on due date you can see when she most likely ovulated and conceived. It's about a week off from when her period would give her due date off, but that's likely because her cycle is longer than 28 days so her ovulation wasn't 14 days after her last period of Oct. 18. It just doesn't add up to be her ex, based on both due date/gestational age or her last menstrual period.

I agree that its unlikely, but to know for sure? Thats another story. I still think the best course of action is to consult with a medical professional. Advice from a forum is nice, but are you going to make decisions based on what PomLover or My3cents has to say?

lol Okay.

may you please help me out my last period was march 26 , i had sex with my boyfreind jun 1 and my ex jun 4 . who my babys farther

Absolutely impossible to tell without a DNA test with that close of proximity. Good luck.
