Birth control/ plan b/ pregnancy test

Madisan

So I been on birth control for years now because I have un regular periods and so on 6/3/19 me and my man had sex and the condom came off some how and he came in me. We both went to the store to get plan b and a pregnancy test just in case. I took the pill but I just noticed today that on 6/3/19 I was supposed to get my birth control shot/Depo shot and right now I don’t know what to do. Is there a possibility that I can be pregnant If the pill didn’t work? I’m also supposed to got get my birth control shot tomorrow but I don’t know if I should tell the doctor that I had sex and that I took the morning after pill. It’s only been 2 days since it happened and I know a pregnancy test wont tell me this soon.
