Coming off Birth Control

Hi there! I've been off of birth control pills for about 10 months now after being on them for 5 years and my periods still aren't regular. There were a few months were it started when it was supposed to but other than that I've been late 1-3 weeks every month and its so frustrating. I get pregnancy symptoms which I know are common when you are about to start your period but then my period doesn't show up for a few weeks. I feel like I'm going crazy. I've been reading and most people return to "normal" cycles after 2-3 months so I'm starting to worry that something is wrong. I plan on making an appointment with my obgyn to talk about it but until then I'll just be here worrying 😂 Has anyone else had this issue or know of anyone who has?
