Glow estimated my period to start on the 8th but it didn't come so it pushed it to the 10th but it still is not here. I don't even see anything when I go to the bathroom like is starting. The Ovia app says I have 2 days left on my period. I had a miscarriage on the 15th of last month and am wondering if I should get a pregnancy test from the store and take it in the morning. What does everybody think?
