Birth Control

I have been off of birth control for a good while now. Over 2 years. I would like to start taking it again as my periods have started being crazy again. I will go months on end without having one and then have one 2 (sometimes 3 weeks) then I may go a few months with a normal period. Previously, when I was on BC my periods stayed regulated and I had no issues minus having to take an extremely low dose. I want to take the pill. No implants, IUDs, or shots. Too many bad reviews. Those of you on the pill how many of you have had bad side effects? Any brands you recommend? Pros and cons of being on the pill?
