Aiyoh, adhesion colic is really troublesome lah, I have a few mum friends who dealt with similar sharp stabbing pains after surgery, and they said it does get unpredictable during pregnancy as the baby grows and everything shifts around. Definitely worth checking in with your gynae soon, especially since you're expecting now, because they might want to monitor it or give you specific advice on managing the pain safely in pregnancy, better to be on top of it than worry throughout. Do let us know how it goes, many of us would love to hear what your doctor recommends!
