Glow is no longer predicting my period?

Kaitlyn

It gives me my predictied ovulation days but doesnt give me my period days. I figured since i had a baby in october it needed a few periods to begin predicting again but ive been getting my period regularly since december and still no predictions.

Is there a way to turn it on? What can i do? I would like to stop being surprised when i wake up and actually have an idea of when its going to come lol
