Brittany's journey to glow

Brittany
Hi all, I am 25 and TTC for baby number 1. I've been with my bf for over 2 years which we were good friends before then. We haven't used protection in over a year saying if I got pregnant we'd be ready but it's not like we were purposely trying for one. But I never got pregnant ?? 
A few months ago we actually talked about trying for one. I have a muscular dystrophy (I would like to have one before I get too weak) yes he wants to be married first but we're going to get married anyways. He knows how bad I want this. 
So I download glow and read some amazing stories. I even tried tracking bought opk's and nothing ?? I have irregular periods. I've went a year without one. Do I ovulate? I spoke with my doctor fearing something was wrong and she assured me that everything is ok it's just hormonal imbalance.  I can still concieve it'd just be harder because it'd be hard to know when I ovulate. 
I'm trying to keep my faith that it'll happen.
