Sayang, situation macam ni kena check dengan doctor atau go to clinic/hospital je, jangan tunggu lagi. Positive test then bleeding and negative again tu bukan benda yang boleh guess, kailah proper scan dan blood test baru tahu apa yang tengah jadi dengan badan kamu. A few of my mum friends went through confusing results macam ni, and setiap case lain, some were just timing issues, some were miscarriage, some were ectopic, so seriously jangan try figure out sendiri, go see your OB or go to A&E if you're bleeding heavy or cramping teruk. You deserve clarity and proper care, okay?
