Alright, I see. You could very well be pregnant. But...That's anytime a couple has sex, there is always a chance of pregnancy. You can't determine it from the pain, though. When I found out I was pregnant, I was having normal period cramps like I do every month. I never would have guessed I was pregnant.
I suggest waiting a week and taking a test, just to rule out the possibility.
But for now...Try some tylenol and a warm bath?
