Ay mamsh, nakakabahala yan pero ito ay fairly common sa mga preggy na nag-bikini cut, lalo na around 27 weeks when everything is stretching pa! A few of us tried moving slower from lying to sitting, like, elbow yourself up first instead of going straight up, tapos pause para ma-adjust ang tahi and the ligaments nang hindi ganap na tension, and it made a difference talaga. But mamsh, since you're experiencing sharp pain or difficulty moving, it's really best to check with your OB kasi they can feel kung ano talaga ang nangyari sa incision area and if anything needs attention. Wishing you relief soon, mama!
