It could seriously kill you, if it doesn't kill you it could seriously hurt your body. Its not safe at all. I would advise it. Have you ever thought about going to NA. I would advise you to do that.
YES! There is ALWAYS a chance you can get pregnant, ovulating has nothing to do with it. Unprotected sex is capable of pregnancy at any time, and STDs at any time. Just be careful. If you are looking to get pregnant, then unprotected sex is the way to go, if not then protection is needed..TRUST ME!!
