I' m 19 and have never had full penetrative sex. However I have fooled around with a boy two days ago. We didn't have sex but we were quite close to doing so and now I'm very worried about the possibility of being pregnant. I was due on my period a week ago and I still haven't come on. Is it possible to get pregnant without actually having sex? We were both naked and pleasuring each other in other means and he wasn't wearing a condom.
