Alaah, cramping ni memang biasa during pregnancy tapi kalau terasa nyilu macam tu, better check with your doctor okay? A few of my mum friends pun pernah alami and doktor dia check untuk make sure semua okay je, takut ada apa-apa. Don't worry, most of the time it's just normal stretching pain tapi takpe, call clinic atau OB-GYN you and describe exactly where and how it feels, they'll put your mind at ease! Minum air banyak-banyak and rest dulu, see how it goes. Jaga yourself okay!
