TTC WITH IRREGULAR PERIODS

Precious
So i have had IRREGULAR periods for the longest DRs tell me its cause my weight but when i was 14 and lost my virginity my mom put me on the birth control depo shot i was then on it for a few years and ttc after a year without taking the shot my periods where crazy lasting months at a time!! Then i got back on the shot to stop the bleeding cause when i was on it i had little to no periods. Anyway I've been off the shot since April 2014 me and my fiance want to conceive. My cycles are short sometimes they come every two weeks will this app help me?
