Question to 2nd/more time C section mommas

Im currently 34 wees, if my leggings or under pants ( elastic) sit on the my c section scar i feel very uncomfortable, short or breath, my stomach gets hard, i feel similar to getting BH. I wanted to know if anybody feels this way, should i be concerned. Im worried because i have scheduled c section , if only for elastic pressure im feeling this way not sure how would i feel at the time of operation. I will have my dr. Appointment In another 2 weeks , will check with her also, mean time to calm my anxiety looking for any ladies with similar experience or any knowledge sharing will be appreciated
