So, I'm 16 days past my EDD. When the midwife checked me Tuesday, I was only 3 cm, and that was after she was digging around a bit. She tried to strip my membranes, but couldn't. She offered an ultrasound, and at the time I thought, no way, but now several days later I'm wondering if it would be a good idea, just to be sure the baby is OK. Thoughts?
