My baby boy moves a lot. Probably 20-30 kicks per hour. For almost 2 months he was positioned completely horizontal. This last week he has moved to straight up and down (guessing head up, feet down or vice versa), and today he has kicked me so hard in the bladder and at times it feels like he might kick straight through to my vaginal canal!! I'm not having any pain but it's alarming compared to his other movements. Plus, I'm only 29 wks tomorrow. He seems to be quite low, more near my uterus than up in my bump area. Should I call the on-call nurse? Or would I be wasting her time? Thank you in advance.
