possible 3rd miscarriage

I've seen the heartbeat due to history of miscarriage and yesterday I noticed blood when checking myself. Today it has got worse and is pink turning red. I've spoken to the hospital who have told me to keep my scan which is booked for Monday I will be 8 weeks. I can't even explain how I feel expect I feel sick so sick and a failure again. My husband is trying to stay positive but I just know it's over again :(
