After you went off birth control, how long did it take for your period to come back? I was on the pill where you get your period every 3 months. I went off it in mid-December and still haven't gotten a period. I tested and I'm not pregnant. We aren't trying but want to try this summer/fall and I wanted to be ready. In 2015 when I went off birth control and had my first child, it took 7 weeks for it to come back and then I had long 5-7 week cycles. I'm planning to make an appointment with m doctor but I was just curious if anyone else experienced this and if you took anything to get it started?
