Not sure if i'm pregnant or not. Here's my story my ex came inside me on sept. 24 early morning like 1:30 and later I found out I was fertile that week. But I was ovulating on the 25th, and today I took a test but it came out negative. So far I have had back aches that was weird, minor cramps, head aches, bloated and a little tired but I don't know if its because of school.I also was a little moody today, but I don't know if it was because I woke up on the wrong side of bed. Which if I was to get cramps they would be three days b4 my period which is the 9th. I don't know if I did it wrong or that it was 2 early. What are your views? Does anyone know how long sperm can last? How long did some of you what before testing?
