I'm not sure what's happening! My period was due to start Tuesday. It didn't come so I pressed on "period Late" and glow predicted it would be due today if late. Still no period. I took a test last night but negative. I know my cycle is around 29-33days. So it should have come. My cervix the other day felt open. Really bad cramping today like I have never felt before. Worse at night. Is this normal for a late period. Do you think there is a possibility of conception even with slightly open cervix? Thank you for your help 😊
