Irregular! Any advice?

Back story:

So when I was a freshman in high school my OB put me on birth control because I was having periods twice a month every month. So for the following years it did just that, helped regulate my periods.

Over the past few years my cramps got so bad during that time that my OB had me skip my sugar pills and go direct you to the next month. I then would have it when I wanted to.

My S/o are going on 6 years together and have been talking about kids more. I stopped taking my birth control almost a year ago in May. Had two light periods and then no period for the rest of the year. Come December to my surprise I started, it was light but I was excited I started. January check. Two months in a row I thought I was getting back to normal.

Now February I haven’t yet had all the symptoms of starting it but nothing. On top of being ready to start a family ASAP I just want to be back to normal. If I would of known it would do this I would of stopped a long time ago. On it for 11 years

Does anyone have any advice to help regulate it?
