I have had a boyfriend from June 6th and we have had unprotected sex all summer he has came inside me everyone we have had sex and I've never been on because in my entire life anyway my last pierod was aug 6th and I found out I was pregnant the 12th of this moth and now I'm 6 weeks pregnant the second guy I had sex with I had sex with him August 11 after my pierod had finished it was unprotected but he came on my stomach I'm pretty sure I had sex with my boyfriend on the 13th and he came inside me like always and I need help figuring out what day I got pregnant!

Nobody of this earth can guess that... you are going to have to wait until the child is born and have a DNA test run... because by the time you get a delivery date, which is just an extimate, you can backtrack 9 months and you would still bt plus or minus two weeks on the conception date.

That means anyone you slept with that entire month might be the father.

And it doesn't matter where the finished... if no protection was used... then you were trying to get pregnant...

And even if protection was used... no form of birth control is 100% effective.

First, please don't keep posting the same question. The others have been removed.

Second, calculating conception dates is an inexact science. Your sexual encounters happened too close together to eliminate either one as the source of conception. You will just have to wait until birth and perform a DNA test.
