I need some advice!

Elva
I had a miscarriage on July I did feel sick the first few weeks but later on I felt great like if I wasn't pregnant I went to go get checked and my baby's heart beat had stopped beating with no explanation 😔 and now I am 12 weeks pregnant I feel great I don't feel pregnant I'm just afraid I'll go through it again my baby's heart beat was 170 when I first heard it and haven't seen the doctor since I'm burly on my 2nd Doctor visit tomorrow morning I'm just scared it can happen again my belly is growing a lil bit but I just feel like its bloated at nights...
