So, I cant fricken remember when I had my period I am pretty sure it is in the middle like 13th-15th ...anyways so my bf and I of 2 years had sex 3 -5 days after my period the middle end of january. He pulled out like always and we have done this for 8 months no problem. However him and I split up. I had sex with a close friend , no protection, doesnt smoke drink or anything and he hadnt had sex for a long time... anyways we had sex on Jan 2 and the 5th. I took a test 2 times on the 7th and 9th it came out negative however today is the 13th and it came out positive...if Shane made me prego by chance it would have came out positive right? That would have been almost 3 weeks. Is it possible that with in 10 days from having sex I could be pregnant with my friends kid and it shows up on a test?
