I have been having trouble having periods all my life. I won't have a period unless I'm taking birth control pills, but I don't take them so I don't have periods. Anyway, I have been having unprotected sex with my ex for 6 years off and on. He usually pulls out, sometimes he don't. Lately he has been, but I am having strange symptoms. I really don't know if I CAN even get pregnant. My breast have never been sore in my life but right now they are so sore I can't stand it, I have been nauseated but haven't thrown up, have bad headaches, and I have been feeling really bloated. So, I guess my question is could I possibly be pregnant?
