Spotting missed miscarriage

Hai mommies. Saya dahh 2 kali scan dari bawah kantung still nampak kosong in 11 weeks. Doktor cakap kemungkinan missed miscarriage. Sekarang tunggu last appointment kalau still same kene cuci. Tapi dalam seminggu ni kadang ade spotting kadang takde, kalau ade pun tak banyak. Perlu ke saya refer hospital?
