I had norovirus start of the week. Before this I'd had instances of light brown spotting. After much vomitting I had heavy brown bleeding requiring a few wipes. Few days of nothing later I have had a large gush of red blood this morning now back to light brown spotting. Went to a&e, heartbeat strong, cervix closed, but told bleeding means I have to consider possible threatened miscarriage. So it's a waiting game. Anyone been through this please?
