I don’t know what to do..

Hi I didn’t know what other forum to post this on, but I just need help. I’m 17 and had a miscarriage about a month and a half ago. Since then I have planned a pregnancy and I’m now 3 weeks (I know it’s very early). I told my mum and she is furious with me and tells me how I’ve ruined everything again (like I did with my previous pregnancy). We live together and I just don’t know what to do. I know my family isn’t going to be supportive of this so I’m lost.

EDIT - I know what I’ve let myself in for, just wondered if anyone has had similar experiences or any advice on how to handle the family situation and how to cope with them potential not having any involvement in mine or my babies life.
