Good day. I'm 12.5 weeks pregnant with twins. One screening showed everything is fine. The detachments have all healed. Three days since discharge from the hospital. Can you tell me how normal it is that my lower abdomen hurts and pulls like during menstruation when I move around? :( I got up from bed, walked for 10 minutes; even tilting my head starts hurting). Bed rest regime from 4-5 weeks Detachments were at 5-6 weeks And at 10 weeks Two times I was hospitalized. In general, is this normal? Or is it really going to be that I need to constantly lie down
