Help im nervous!!!!!!?

A simple spot could get a girl pregnant. So most likely she is if you did not use anything. Her having a stomach ache could just be a stomach ache, but she shouldn't be having nausea, or vomiting, those are the number one symptoms of pregnancy, the sensitive are normal, all women get the sensitive before getting the period, but the only way for sure if she is pregnant is to get tested once she is at least a week late from her period. And if she is I would suggest adoption. Don't let abortion cross your mind. Maybe you are too young to be a parent so think about adoption, and next time make sure she is in birth control, and you do your part, and use something also.
