Sayang, cramps ni memang boleh jadi normal dalam pregnancy, tapi kerana ada sejarah C-section dan first time rasa macam ni, please go see your doctor or go to the clinic to get checked , tak perlu risau, just to be safe je, okay? A few of my mum friends yang ada previous scar juga rasa macam nyucuk-nyucuk sometimes, but it's always best to get the doctor to confirm everything is good. You and your baby are precious, jangan nak tough it out sendiri. Praying with you that everything goes smooth, sayang. Kuat okay!
