I have what I realize seems like a super silly question, but it has me concerned. I am 20 weeks pregnant. Last night, while removing a pair of tight fitting undergarments (Spanx), they became rolled and very tight right around the area where my baby is. Without thinking, I pulled hard on the back to remove them and it put a great deal of pressure on my abdomen. I gasped in pain because it felt funny and somewhat painful. I am worried sick that I've hurt the baby as I haven't felt him move much at all today. Of course, I have only been feeling tiny flutters from time to time as it is. I had an ultrasound yesterday before this happened, and baby looked fine. As I said, I know this is a silly question, but I need some peace of mind. Can an incident of very firm pressure/pushing on the abdomen harm my baby?
