Frustrated

Amber

My Fiancé and I have been ttc for about 4 months now the problem is I have very irregular periods sometimes I go a month and a half in between and sometimes I skip a month . I got off depo about 2 years ago after being on it for 2 years I have always had irregular cycles. Any advice would be greatly appreciated it . I'm starting to get discouraged. Please help . Btw this is 13 DPO.
