I wouldn't call it cramping....

This is my fourth baby and will be having my fourth c section. I don't know if it coincidence or not... I am 10w 3d.  My 30lb toddler has croup. He's sick and wants to be picked up and held 24/7. Obviously, proper mechanics were not applied. I am also absolutely exhausted... Which leads to the abdominal discomfort. It feel like I worked out too hard (as if). I have had a couple of episode of round ligament pain which has stopped me dead in my tracks as well. I feel pulling on my c section scar which I def had with my 3rd. All that and here's the question... Anyone else have uterine stretching pain around now or experience straining your abdominal muscles from lifting? And c section mamas have their scars ache? My gut is telling me this is fine which I why I am not in an ER. Just figured I would ask.
