Hey everybody~ i'm new here and i'm extremely confused about myself. I'm 17 years old, and am very unsure of wheather i'm pregnant or not. This is a first for me. I'm unsure of the date of my last period although I believe it would have been around the 23rd. I had unprotected sex with my boyfriend on sept. 2nd, 19th, and 20th. I just recently have started feeling sick to my stomach quite often, but I also know I have a stomach ulcer. I'm usually never late with my period. I took a test sept. 19th (morning), sept. 21st (evening), and sept. 22nd (evening) all coming out neg. We have used the pull out in time method and saturday kind of went a little bad. He says he made it out in time, but he ended up getting on me just not on the inside (he doesnt think). What should I do? Is it all just in my head?
