When can I expect my period after stopping the pill mid-pack?

Eve • TTC with my husband 💍 | one chemical pregnancy

My bf and I had a pregnancy “scare” a couple days ago which turned out to be negative, but since then we decided to start actively trying. This means stopping my birth control.

If I still took the pill, my period would come in 3 weeks. (I only get my period every three months on bc). Should I still expect the same time frame? Or earlier?
