To test or not. That is the question.

We had a miscarriage in April at 10 weeks. I stopped using the app for a month or so. Well now my period was supposed to start on the 4th. It hasn't and glow just keeps pushing it back two days at a time. My average cycle is 29 days. I'm now on CD33. I don't want to get too excited but i don't feel my period coming either. Advice?
