need help

Okay so my periods just started to regulate a month or two ago from being off the depo shot. Glow said my period was due 10/31 I never got it. And every time I put my period is late it pushes back my period and ovulation date back. So is it possible I ovulated later than what it told me I was suppose to. Because I got ewcm later than the ovulation date glow is saying ?
