Hey mama, that's actually something best checked with your OB talaga, small bumps or lumps inside the belly during or after CS recovery can be a lot of things, from normal healing tissue to seroma or other stuff na kailangan tingnan ng doctor para sure. One of my mum friends had something similar after her CS at kinilala ng doctor agad kung ano, so don't worry pero go get it checked soon lang para sa peace of mind mo!
