Wa'alaikumassalam sis! Eh, this is something you really need to check with your doctor or OB/GYN asap, jangan tunggu lagi, okay? At 9 weeks, the heartbeat should usually be visible on scan, so better get a proper check-up to make sure everything's okay. I know it's scary, but doctors need to assess this directly, bukan kat sini boleh judge. Go see your doctor hari ni kalau boleh, they'll do proper ultrasound and give you the real answer. Take care, praying for you!
