Stressful first Sex experience

Hello ladies, please help! I had sex almost two weeks ago and it was my first time. The guy took the Condom off without telling me but luckily while he was still going I noticed that I was bleeding and told him to stop, which he did. He was still hard and afterwards I sucked his dick and he came. Is it possible that he could have came inside me while we had sex even though he was still hard/and could cum 10 mins later. I didn’t take the morning after pill because i didn’t know he took it off until he recently told me but I’m stressing so much and I’m so angry at him.

(My last period was on the 24th of December and due tomorrow I think but I have no period symptoms yet)

Edit: he said he didn’t cum but he might just be saying that so I don’t get worried. And I’m well aware that Precum can get you pregnant :(

I’m not on any contraceptive unfortunately
