I'm 17 years old and about two weeks ago "kind of" had sex for my first time. I've been on birth control now for 4 months and when we tried to have sex two weeks ago the guy wasn't wearing a condom. We tried to fit his penis inside but it wouldn't go in all of the way without feeling pain so we stopped. It was literally in for a matter of seconds. I've recently started not feeling well and the symptoms are similar to what you would have when you're pregnant. I'm kind of freaking out because he didn't even cum but I know there is such a thing as precum. I also just started a higher dosage of adderall and don't know if this could be the cause for why I'm not feeling well. I've had a constant headache, I was having nausea but not anymore, and my stomach has been hurting and feeling kind of crampy. I'm supposed to have my period in 9 days but don't know if it's going to come. Do you think I'm pregnant?
