Once you stop taking birth control pill, is your period usually pretty regular from that point..? Second month since I stopped and the prediction last month was correct but this month I was suppose to start yesterday...so far nothing. I don’t want to get my hopes up, since it’s one day off so far lol. We had tried on the highest ovulation predicted days, but now I put my period didn’t start yesterday and it changed everything? Just don’t want to get my hopes up for nothing
