Very nervous I could be pregnant. CALM ME!

I am lowkey freaking out but everyone tells me not to.

My average cycle length is about 24 days.

I had my last period 17th - 20th of July.

My next period is supposed to start the 13th of August.

I have been on birth control for about eight years. Recently I broke up with my boyfriend and stopped taking it as consistently. (Forgetting Wednesday night so taking it with Thursday’s pill) I don’t know how often it was or how long it was like that.

I ended up having unprotected sex August 2nd and he got all up in there. Around 1:00AM Saturday is when he came inside me. (We were both drunk and I did not expect it) and around 2:30PM Saturday I took plan B.

I read that it can take your body time to adjust to being off the pill (which I never really was, just taking it inconsistently) so it could take as little as a couple months to about a year. On top of taking a plan B so soon, is there a good chance I could get pregnant?

I took ovulation calculators (like 8 of them) and all said my “fertile days” ended before July 30th. Not sure if or when I was ovulating.

NEED ADVICE!
