Im about 29 weeks pregnant and my son plopped down very hard on my stomach he is 2 and weighs 30 pounds. My stomach has been in a lot of pain since. The baby was moving right after but has since stopped being active in a matter of 30 mins or so. It hurts the worst on the opposite side of where he plopped down on me. Top left side of belly by my ribs. I dont know if thats where my placenta is or not but it really hurts. Should i call my obgyn office? I just dont know what to do and the pain wont lighten up. Im very worried for the baby.. i know they are very cushioned in there but my placenta is on the front.
