Regulating cycles after birth control?

What helped you get your cycles on track after BC? It’s been a few years & im very irregular now. Sometimes every 2-3 months. Ive been taking fertility premama for abt 4 months & it’s helped so far getting a cycle each month but they’re 44 days. This month I had a very light spotting period & I normally have medium-heavy flow. Don’t want to get back in BC to regulate. Currently ttc! I will try anything to help regulate my cycles! I have my appt w/ my gyn in a month but feeling stressed out bc I’m scared.
