Possibility of getting pregnant during your period..

So I had sex with my boyfriend the day before I got my period. This time was different than any other because he actually released inside of me. I guess I’m just wondering if there is still a slight chance of pregnancy happening? It’s been about a week since I’ve finished and I’ve been having period cramps it feels like but not as bad I haven’t seen any spotting yet. I have been extremely tired like I could sleep standing up at work. My body just feels a bit different but I don’t know if it’s just my mind overthinking. I know for sure I am feeling what I’m feeling though I just wanted to see if there was or still is a possibility of getting pregnant during that time. Thank you in advance to you wonderful ladies for your input I appreciate it truly 💛✨🕉
