Can pregnancy make your urine smell musty?

I've just noticed this weird smell when I pee and I want to know if it's a sign of pregnancy. I recently got off my period and I noticed the smell the day after. It was really strong the first day I noticed it and while it's not as strong now, I can still smell it if I pay attention to the odor. Is it a sign of pregnancy? I had anal on the last day of my period, a few hours before I noticed the smell. I'm waiting until I'm closer to my next period to take a test.  Also, please tell me if I'm just being paranoid.
