Cramping memang boleh normal dalam pregnancy, especially kalau takda bleeding atau discharge yang weird, tapi sebab ni bulan ke-4 dan you dah rasa cramping 2-3 hari berturut-turut, better check with your doctor or midwife je untuk peace of mind, tak perlu tunggu lagi. A few of my mum friends experienced cramping on and off during first trimester and everything turned out fine, tapi each pregnancy beda-beda, so better tak ambil risk kan!
