Ay anak, if the cough is that painful and you're worried about your incision, please see your OB or go to the nearest clinic/hospital right away, hindi dapat mag-alala ka nang mag-isa about this, kailangan mo ng professional check. One of my mum friends had a similar scare after her CS, at sabi ng doctor niya, it's always better to get checked kaagad para ma-rule out any complications. Praying you're okay, ha! Keep me posted, and don't delay, your health is so important, lalo na ngayon na kailangan mo pa ng energy for baby. Malakas ang prayers namin sa inyo.
