Shud i tell mii mothr dat i preg agen (i 15yo !)?

You're a completely irresponsible. You definitely should not be having with morals like yours. You're fifteen and have with 50+ people? You need to tell your mother. Give this baby up for adoption too or have an abortion. You clearly cannot raise this baby yourself. I hope you're kidding, but if you're not, you need to go to a counselor and a doctor. STD's and more babies are definitely in your future. Or at least get on some kind of birth control for heavens sake!
