bleeding after sex

need help i’m overthinking & getting anxious!!!!

had sex, on top the entire time.

my two <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> apps say i’m in the last day of my ovulation week.

we get done and i go to the bathroom and fine but after a while i notice i feel wet and assumed it was discharge until i got home and see blood.

it was pretty fresh looking bright red blood. it was a decent amount of it too. enough to bleed through my panties and shorts.

google told me all sorts of things and one of my main fears is that it’s implantation bleeding.

i also read from other girls on here that really similar things have happened and it’s most likely just from knocking the cervix.

is there a way to differentiate what could have caused this bleeding?

i want to assume it was my cervix being irritated causing bleeding but i didn’t bleed when i lost my virginity nor have i ever dealt with a situation like this.
