Irregular AF

Went to the doctor and she pretty much came to the conclusion I may just have irregular AFs and that most women get on BC to regulate it than get off and get pregnant my question is should I try that before I go see a fertility doctor or ob/gyn cause she also referred me to one of those too but idk what I should... did the BC thing and I still haven't but I only went on it to ease the cramps.... I NEED ADVICE PLEASE
