Stopping birth control

Hey!

The last day i took my birth control pill was sept 21st. As me and my bf we’re going to start TTC. My period was suppose to be here this last week and no sign of a period. I took a pregnancy test oct 1st and it said negative. I know stopping birth control can screw up your period but how long did it take for u ladies to get yours after stopping birth control?? I’m going to take another test sometime in the next couple days. But the unknown is killing me right now 😂
