First Time Happened! Help!

So I officially did it with this guy I’m head over heels with! He was ridiculously respectful and patient with me and it was an interesting experience lol.

The thing is I’m 21 and right when it happened, I bled. Now I’m 150% aware that I’d bleed on my first time BUT! Literally and hour later, I got my period. Is that normal??????? It came like 2 weeks early and I do have a history of my periods coming tremendously early and am on birth control for it.

But no one ever told me that sex could make your period come early. HELP
