Glow charting help!

Kylie
So glow says im on day 31 of my cycle. Af supposed to come yesterday. My average cycle ranges from 27 days to 29. No symptoms except lots of bloating the last week and some very very slight cramping below my ovaries (more like a twinge) like once or twice every couple of hours. I would hate to take a test and then af come and me end up wasting my money but im also too anxious to wait a week. Any ideas how to get my mind off the baby stuff?
