What Are The Chances of Pregnancy?

hi everyone, i am 20f. i’m on the combined birth control pill.

i’m always pretty good about taking the pill, i typically take it at night between 9pm and 1am.

about a week ago i had unprotected sex with a new partner and i ended up falling asleep at his place and not taking birth control until the next morning at around 9am. during sex, he did not finish, but i know that sometimes that does not matter. as for the pills, it was towards the end of my first week of the pack, as i had just gotten my period the week before.

that day and the day after i had pretty bad cramps and some bleeding the day after. at first it was dark red and brown, and then it was brighter red. today, (about a week later) i had slight cramping and a small bit of bleeding that was dark red and brown again.

i’m really nervous about the risk of pregnancy here, i’ll take a test soon when i would get more accurate results, but of course im freaking out in the meantime. any advice or anything is very appreciated. thank you so much in advanced!
