Did losing my virginity bring on my period 4 days early?

I’m 22 years old and just lost my virginity 4 days ago (Wednesday) to my boyfriend. We tried out a few things and he gave me oral which I believe I orgasmed and came from every time. Then when he tried to put it in it hurt quite a lot because he is quite big so we used lube and he managed to get it in with me being on top, he didn’t cum at all and we used the same condom while we tried to get it in, the condom may have moved a little from the bottom of his dick but he rolled it back down, now since he didn’t cum is there any way I can be pregnant? The condom didn’t break but if there was any pre-cum could it have moved down the condom while it slightly slipped down?

I also noticed a little blood after penetration when I went to pee but it was only spotting, which I know can be due to the hymen being stretched/torn. I wasn’t in any sort of pain.

The next morning we decided to have sex again and this time it went in easier, I orgasmed from oral again but I was still spotting, he did cum this time but he pulled out before he did and there were no tears in the condom.

When I went to work an hour later I noticed the bleeding had become heavier but I wasn’t in any pain I felt great, legs were still shaking. My period was due 4 days from the day I had sex and they are quite regular give or take 1/2 days.

It is now 4 days since we’ve had sex and I’m wondering did sex for the first time bring on my period early? I’m still bleeding but I can’t tell if it’s my period or if I’m torn inside. I’ve started cramping and getting some ovary pain every once in a while and I feel bloated at times but it comes and goes. Should I be worried and can I be pregnant at all?

Please no hate it is my first time, I was emotionally and physically ready to do it I just need some advice as of course having sex for the first time is a massive change.
