Menstrual after depo

Kristi

Hi everyone so I have a question. Does anyone else when they first missed their shot, started having a period within a few weeks? But yet miss one month? I missed my May one and I ended up starting like end of May but then June I missed my period completely and July almost till near the end. Is that normal? I know it not going to happen away getting pregnant but when does people see more of a consistency in their cycle?
