Pregnant and can’t be excited ?

I’m 21 and I’ve had 3 miscarriages, well I just got a faint positive yesterday. I don’t know what to do or how to feel I’m so use to having miscarriages I don’t know what I would do if I didn’t. I feel bad saying this but It’s not that I want to have another one because it was terrible and I wouldn’t wish it on anyone I just don’t know how to feel .....
