Miscarriage

Br

Just need some positive words of encouragement. Last Saturday I found out I was pregnant and on Tuesday my level was 40 and then 60 and is still 60. My doctor says I’m going to miscarry. I’m absolutely heart broken. I have to go again for blood work on Monday to reassess my levels and make sure they drop. It’s very early on but it’s still crushing me. How long does it take to miscarry?
