first time sex

Hello!! I'm 17 and I had sex a week ago during my ovulation for the first time. He wore a condom and didn't cum, but I am still anxious and worried about being pregnant. My tummy cramps up sometimes but not severely, I pee a little more lately but not like crazy, and my breasts are a little sore. Those are pretty much the only symptoms of pregnancy I'm showing. Am I going through something normal or could this be pregnancy? Again, he didn't cum and we used a condom the whole time.
