pain in stomach after sex (help)

I lost my virginity about two months ago and ever since then I've been having constant stomach pain. In the first couple of weeks I was always feeling hungry and/or like I had to throw up.Lately i've just been having stomach pains. I've had my period since the last time I did it, but I heard some people still get there period when they're pregnant. Do you think I could be pregnant or it could be some kind of bigger health issue?

If you had a normal period then it is unlikely that you are pregnant, but you could take a test to confirm
