is there a possibility i could be pregnant?

i know i might sound paranoid, but i just want you guys to know that i have ocd, especially regarding health/pregnancy. i am medicated and go to therapy, but i’m going through exams at my college and i believe the stress is making me spiral again.

now, i take birth control. i had sex on may 14th with a condom. the week before that, i believe i took two pills a little later, but i think i still took them within the correct time frame, if i remember correctly (i usually never miss any pills, but i wasn’t home those days so it slipped my mind). on may 22nd, my period started and it ended on may 26th. i started a new pack of birth control on may 25th and, in the last week of that pack, i failed one pill. so i did what the birth control’s leaflet says: i resumed taking that pack normally and, on june 15th, started another one, with no pause for my period to start. now, my period was supposed to start today, but it hasn’t.

is there a chance i’m pregnant?
