Good day girls! I recently went into labor but they wanted to call it premature. They sent me home the next day. On the 10th, I went to the clinic and was sent back to the hospital. I'm supposed to be at 40 weeks, but I haven't had any pain yet. I'm thinking of going back to the hospital or waiting for it to start on its own? ? The baby kept turning over all night, causing pain in my back and lower abdomen. It turned over to the other side, everything is fine now. What could this be? ?
