type of miscarriage?

Samantha
So I went for a scan yesterday and it showed a pregnancy sack but no yolk sack- unable to tell if I've just got irregular periods and I'm actually only 5w (whereas I should actually be 7) - today I've passed what looked like a more squishy cod liver oil tablet but clear (and popped when I pressed it) and I've started bleeding heavily. So spoke to midwife who agrees this sounds like miscarriage and I'm going for a scan tomorrow to confirm. What kind of miscarriage does this count as?
