Miscarriage ??

I've had unprotected sex but he pulled out. I went to the doctor a week after and She haven't said I was pregnant so I'm guessing I'm not considering I had took a pee test anyways but lately I've been having bad cramps very very bad cramps I don't get it because I'm perfectly health angers it's been 2 months now and I still have bad cramps is it possible I've had a miscarriage ?
