7 months ago i had unprotected sex, and he pulled out (i know that really doesnt make a difference) and i had my period on time, and it was normal, but after that i didnt have another period until febuary (about 5 months) and that one lasted almost the whole month, and was super heavy, which is why im confused. Im really worried too. Im not ready to have a child, yet alone want one. I dont know what else i can do. Im only 17.
