Coming off of continuous BC

caroline
Hi all! My husband and I are newly TTC -- I finished my last BC pack last weekend. I was diagnosed with endometriosis 8 years ago and so on the advice of my obgyn have been taking my birth control continuously to try to alleviate the symptoms and hopefully make pregnancy more likely. 
We are so excited to start trying, but given my history and age (I am 35) I am also nervous and trying to be realistic. First bridge to cross is to get my period back! Anyone take BC continuously for a prolonged period? How long did it take to get your period back? 
Thanks so much!!! All advice/insights appreciated :).
