Alternative to birth control? Please help!

So I am wondering if there is medication out there to regulate periods besides birth control. My husband and I are trying to conceive but my periods have been really random since stopping my birth control. I stopped it in may and missed my June period. I had one in July and August. Missed one in September. Had one in October and now according to glow I am late for the month of November. I took a pregnancy test and it's negative. I don't think I'm pregnant, I think my periods are just messed up. If anyone knows of anything I can do to regulate my periods without birth control or contraception that would be great!

Also I have a referral for a new gynecologist but I have not gotten in to see her yet as she is booked way out so going to the doctor is not an option unless I see my pcp, who referred me to the gynecologist when I missed my period in September.

Thanks!
