Miscarriage

Lost my daughter when I was 21 weeks and 6 days pregnant in September. My doctor said it was okay to try again. December 28 I took a pregnancy test at home and it was positive! Went to the hospital to confirm and again it was positive, but then I was spotting and it continued for a few more days. My HCG level was at a 48, they ran more labs 2 days later and found that it dropped to 19. I didn’t even have enough time to react when the doctor said it’s looking like a miscarriage. Really don’t know how I’m going through this again.
