Second miscarriage

So in May I miscarried at 6 weeks. The doctor told me if I get pregnant again I should call to do blood tests. So now I’m 5 weeks pregnant and had my blood tests and it looks like I’ll miscarry again… I’m not bleeding yet and I feel like I’m just waiting around for death. What’s the point in getting my hcg levels checked if they can’t do anything to prevent me from miscarrying? I don’t understand.. now I’m just depressed, waiting to start bleeding again. I almost feel like it would have been better not knowing. At least I’d have some temporary happiness. I’m so incredibly depressed and angry.
