Pregnancy/Period Question from a Boyfriend?!

Pregnancy/Period Question from a Boyfriend?

Alright, I'm 16, My girlfriend and I have not had sex and don't plan on having it for a long while. We have been together about ten months and we have both received oral sex from each other and I've fingered her too. I know you cannot get pregnant from oral sex but she has missed her period and it's been about a month and a half now. She's 15 and she has never missed it before and she now has and she has felt sick recently with stomach pains. All of this is scary the hell out of me and I need know what this could be besides pregnancy. We have done nothing of high risk and I didn't finger her with semen on my fingers so that can't be it. Please HELP

She's a very well brought up girl. I was the first guy she ever kissed and the first guy she's ever done anything as in sexual activities with. She hasn't cheated on me.

It sounds normal. Girls usually skip their periods every now and then in the first couple years of having periods and the stomach aches could be from stress. Have her go to the doctor to make sure but it sounds normal since you didnt have sex yet and if youre sure she hasnt cheated on you. Shes probably just overstressing. Hope I helped.
