“Irregular” Periods...

Hi Everyone, I just thought I would throw this out there and see if anyone has the same issues as me. I am 25 years old. I have always had irregular periods. Didn’t start my period till I was 16 years old, then after that I would get a period and then not get one for 3 months, then get another, and then not get it again for a long time. I started the birth control pill to get them regulated when I was 21. When I did that they would come every 28 days, which was good. But about a year about I didn’t want to be on the pill anymore and now my periods are back to being extremely irregular. Sometimes I don’t get a period for 50 days... Does anyone out there have the same situation as me? Does anyone have any recommendations of what I should maybe do or if this isn’t really that big of a deal? Thank you!
