Girls, hello! I'm at 40 weeks and 6 days. Yesterday, my lower abdomen felt a bit sore, then it stopped, but last night it really tightened up, then let go. I thought it was starting! No, today in the morning it also hurts like during my period and lets go, I don't know what to do. They said to go to the clinic today with an appointment so we can go to the maternity ward. I have no strength, I'm lying down if anything call an ambulance.
