Oh dear, period-like cramping at 8 weeks can feel so worrying, and it's completely understandable you feel anxious especially since this is your second pregnancy. Since it has happened 3 times already, I think it would be best to check with your doctor again, maybe request an ultrasound just to make sure everything is okay with the baby, as cramping at this stage can have a few different causes that only a doctor can properly assess. Makan Coco Crunch dengan susu pun okay for now, yang penting ada something going in, take care of yourself sayang.
