I had sex with my boyfriend last week on Wednesday, which would be May 15th. It was unprotected and I am not on the pill. I have had headaches, been bloated, loss my appetite, and have been extremely tired. I even left class last night to go home and sleep- and I slept for 13 hours straight. I know it is too early to take a test, but could I be pregnant... or could my mind just be tricking me?
