How long did it take you?

Since it is the beginning of the month I haven’t gotten my period but the question is could I end up pregnant from this? Even though I haven’t gotten an actual period since the pill? Not sure if I’ve ovulated. So I took my last active pill I believe on friday april 13th. After that a couple days after I got my “period” then I decided to not start the new pack. Last night May 5th my fiancé and I had sex and it happened so fast we didn’t realize that we didn’t use a condom since it was the middle of the night... he did cum in me and I had an orgasm. Before last night we would use condoms.
