Wa'alaikumassalam! Aah, I understand lah, at 33 weeks with your second pregnancy after a C-section first time, those sensations can be quite worrying. The pulling and cramping sensations around your scar area when baby is active are actually quite common among mums who've had a previous C-section, a few of us mums experience it jugak, tapi it's definitely something worth mentioning to your doctor at your next checkup, especially since you're already 33 weeks along and due date is coming soon. Better to get peace of mind from your OB directly, because they need to know the exact location and frequency of the pain to make sure everything is okay with your scar. In the meantime, try to rest when baby is very active and avoid heavy lifting, and if the pain becomes really sharp or you spot bleeding, go to the hospital straightaway, okay? You're almost there, mama!
