Irregular Periods - Driving Me Crazy!

Sa
I'm 30 years old and ever since I first got my period (14) they've been irregular for the most part. When I was 15 I had a grapefruit-sized cyst on one of my Fallopian tube's and since then have had a history of ovarian cysts. I was put on birth control to prevent them and it worked great. 
Fast forward to my 20's-now and I've been on and off birth control mostly because I hate being on it. My family (both sides) has a bad history of heart disease, and I've had high blood pressure since I was 23 (and very active and healthy weight). 
I've recently been tested for PCOS & thyroid issues which both came back normal. 
Last August- this January  (6 months) I didn't have my period. 
This February and March I got it. 
April, May, & June... Nothing!
My doctors just tell me to keep trying and in a few months I can make an appointment to get some help in the process. 
Anyone else have similar issues? 
Or natural recommendations to bring Aunt Flow back??
If you've read all this, thank you!! I'm just getting so frustrated with all of this!
