Aduh, I can hear how worried you are, and it's totally understandable la given what you're going through. From what I've heard from friends and mums around me, spotting or light bleeding in early pregnancy memang boleh jadi normal, sometimes it's just hormonal changes or the cervix being sensitive, tapi when it comes with strong cramping macam period pain dan berlaku beberapa hari like that, it really does need proper checking with a transvaginal scan to make sure everything is okay. The fact that your first clinic couldn't see much on the abdominal scan is a bit concerning, so I'd really suggest going back to your doctor (perhaps somewhere yang ada better ultrasound equipment or a specialist) for a proper look from below, just to rule out anything like ectopic pregnancy or confirm the pregnancy is progressing as it should. Jangan worry terlalu banyak but please do follow up with your doctor soon, better to be safe, and they can give you the reassurance (or early intervention) you really need right now.
