Sayang, at 4-5 weeks mild cramping on and off boleh normal, tapi because you're early preggy and cramping can mean different things, please text or call your doctor/clinic today to check , better safe than sorry, okay? They might want to see you or do a scan to make sure everything's good. In the meantime, rest miri, drink plenty of water, and jangan stress. If the cramps jadi heavy, bleeding, or you feel dizzy, go to A&E straightaway. Let us know how it goes!
