I had my period April 23 2013; an I had unprotected sex with my friend on May 02 an he didn't pull out; an then on May 05 I had unprotected sex with my ex boyfriend an he didn't pull out neither an on May 22 I found out I was pregnant an my due date is Jan 28 2014. I have tried many conception date calendars which said I conceived around May 07 an I don't know which guy is the father of my child ; my friend told me it had to be the guy I had sex with on the 2nd because sperm lives up to 5 to 7 days inside the body an I was 2 weeks on May 7 then my cousin did some counting an said whoever I had sex with on the 5th has to be the father I really am just confused an I know I shouldn't stress but it's been stressin me an It stays on my mind all the time I sometimes forget an then it comes right back up in my head :( could yhu please help me I have never been so embarrassed
