Baby loss

Hello my names vikki 

I got pregnant last year and I went to my midwife appointment and my midwife did my bloods and everything, anyway I went for my scan at 8 weeks and everything looked fine and then I went for my 12 week scan and the nurse couldn't find a heartbeat so from that point I was in such a mess as having a baby is all I've ever wanted! I chosen to have my baby removed and the nurse came over to me and asked if I knew if my blood type was rhesus negative and I said no as I didn't know what that meant, so my question is should my midwife at my first appointment have told me about my blood type? I'm so confused..
