Could I get pregnant?

Nayy

Okay so me and my so had sex while being on my 4th day of my period. I read online that some girls periods stop after having sex while being on their period but mine didn't stop I went to the bathroom hours of being done having sex to go pee and blood kept coming and through out the day I spotted. My concern is could I get pregnant? He didn't cum inside me. I would like to hear your guys opinions.
