I bled!

So I know that’s normal, he was not my first but the thing is that I bled for a couple hours, then it kinda stopped and I then started bleeding again for a day or so. Why would that be?

We had sex about 5 days before my next period which I still haven’t gotten (eve estimates about 2 days left till I get it) & I was wondering if there’s a chance I could be pregnant. He didn’t use a condom and didn’t cum but I know there’s such thing as precum, help?

-no contraception

-only my 2nd time having sex, I didn’t bleed the first time
