Oo mama, totally normal yan sa third trimester lalo na kung third cesarean mo na, ang iyong ligaments at muscles are really stretched out na from previous pregnancies, kaya mas vulnerable sila ngayon. A few of my mum friends who had multiple cesareans complained ng same thing, that heaviness and soreness ay tumatagal hanggang delivery talaga, pero definitely mention it sa OB mo next check-up para ma-rule out kung may complications at for peace of mind!
