Help!

I am super frustrated today. I was freaking out today because I got a positive pregnancy test this week, putting me at four weeks and my levels on the 19th were 34. On the 21st they were 36 and only increased by two in a two day period. But today I found a doctor who would see me and redraw. And my levels were 55. So it went from 36 to 55 in 24 hours. I’m in a miscarriage support group for moms trying to conceive and despite me commenting and saying that I had just had a draw and it was 55 and the doctor said it was reassuring and to not be too concerned people started to comment that even with me being 55 today it still didn’t look good. I’m just mad because it feels like my reassurance has been taken away even though my doctor said not to worry
