Last month around the 18th I had unprotected sex with my boyfriend and I was supposed to start my period on the 20th. I missed that period. I am only 15 I am too young to have a baby and my mom would kill me! Please help. I have talked to my boyfriend about it and he said the best thing to do was to get an abortion if I was pregnant. I donât believe in abortions and if I am pregnant I wouldnât want to give the baby up for adoption. Please help me.
