So I had unprotected sex with my girl and she got her period day after. I didn't cum inside her. Pulled out about a minute after going in just with the head of my penis. I know there is a chance. But she had her period the day after. I assume she isn't in her fertile stage because of that so she is past ovulation. Her period lasted 7 days so I assume any precum with traces of sperm was flooded out. I urinated before the intercourse. Our chances? This was on the 31st of December
