Am I pregnant?

Maddie

My bf and I have unprotected sex all the time but he never actually finishes in me. My period is late all the time and is 3 days late right now. I know pre cum can get you pregnant but I’ve heard that if a man urinates before than theres no sperm in pre cum so its fine ....? Just want to clarify. I think I’m not pregnant but just wanted to ask.
