Aiih, spotting at 4 weeks dengan cramps macam tu mmg boleh jadi scary! Tapi saya kena suruh you go see your doctor or go to A&E tonight je, nak sure baby okay and takde apa-apa yang keliru. A few of my mum friends ada experience spotting awal pregnancy, tapi each situation lain-lain, so please get checked out ASAP ya, doctor kena tengok condition you properly!
