I just found out I was pregnant. I can't remember my last period but I know that it was somewhere in the middle or end of June. I'm guessing around the 20s. Me and my ex boyfriend had unprotexted sex either the last week of June or first week of July. We broke up and stopped seeing each other for good. I had sore breasts and the feeling of my period coming on a week or so after that. I didn't think anhything of it and started seeing somebody else. We had sex on July 16th and it was protected. And we had unprotected sex but only 2 days before I took my positive pregnancy test. I know that it is almost impossible for a pregnancy test to come up positive only a week after conception, but I still feel worried about who the father might be only because I'm not 100% on all of my dates. Please help. Its stressing me out so bad!

And until the baby is born and you do a DNA test you will not ever be sure.

Best guess is ex boyfriend, but when you say protected, I assume you mean condom, which of course I am sure you are aware has a 3 to 10 percent failure rate.

Yes I agree the sex one week before, would not show up a positive test.

Also even latter when they come up with conception dates those are only estimates and good at give or take a week, sometimes even two.

So sorry, no way at all to know, we can guess with you, my guess is EX. But it could be the new boyfriend.
