Had sex the day after my period :(

Hi, so I lost my virginity like 2 days ago and I was still slightly bleeding from my period (it either ended that day or the day before). It wasn’t a planned thing so he didn’t have a condom but I know he pulled out then we did it again the next day (still unprotected. Yes you can yell at me but Ik it was wrong). My fertile window isnt until the 16th but I was just wondering the chances I could be pregnant. I’m 16. I’m not rlly worried that I’m pregnant but its still just in the back of my mind. Thank you 💕
