Irregular cycle 40+ days post BC pills

Hi everyone, i came of my birth control pill in October, since then I’ve had irregular periods, some as long as 6 weeks apart. How many people experienced the same thing? How long did it take you to become regular and get pregnant. Before I started the pill as a teen I used to have a very regular cycle. Not sure what I should expect, or how long I’ll stay this irregular. Encouragement, thoughts?? Thanks!
