Sex while on period

*DISCLAIMER* I understand that the chances are slim but still would like your input 😊

So my boyfriend came into town 1/21/21 which was the second day of my period. We had sex and he finished in me. By the third day of my Period it was light during the morning but was completely gone by mid day. We had sex again 1/23 before he left but he pulled out (silly I know 😂🤦🏽‍♀️). Is it possible to be pregnant? My period doesn’t start for another 13 days. And this would be my second child she’s 6 so I don’t quite remember all my symptoms of when I had her
