Aduh, cramping at 5 weeks macam tu memang scary! Please go see your doctor or go to A&E sekarang juga, especially kalau the cramping is severe or ada bleeding, better safe than sorry at this early stage, ok? Sambil tunggu appointment, try to rest and drink lots of water. A few of my mum friends went through early pregnancy scares and the doctors checked everything to make sure baby ok. Jangan worry sangat dulu, tapi definitely check with doctor hari ni juga. Take care!
