Hello everyone, I'm at 40 weeks of pregnancy and today started feeling my belly tighten but it wasn't very painful. Well, as with menstruation, and lasted for 7 minutes then 10 minutes, then none, then again 7 minutes and that's all. It hasn't started again. I don't know what to do. The water hasn't receded, the mucus membrane hasn't gone away, and the plug also hasn't gone away.
