Sayang, this sounds really worrying and I can feel your stress. Pergi jumpa doctor atau emergency clinic sekarang juga , heartbeat baby tu penting sangat, dan irregular periods boleh affect dating scan, so kena confirm betul-betul dengan ultrasound yang proper and a doctor's assessment. Jangan tunggu lagi, okay? I know the waiting is scary, but seeing a doctor today will give you real answers instead of the back-and-forth worry. Sending you strength, mama.
