Miscarriage and D&C

kay

Hello everyone, so me and my husband have been ttc for 3 years, January 13th 2019 we got our first positive after having a ultrasound 3 weeks in a row because they were trying to see how far along I was, the sac measured 6 weeks 5 days but it has been empty since our first ultrasound I was told I’m going to have a miscarriage because I’m getting bad cramps and my hcg only went from 400 to 500 in 6 days which isn’t as high as it should be. So my question is this, since my doctor scheduled me for a D&C on Tuesday How Fast Can I get pregnant? I was told I will be more fertile after surgery? Has anyone had this procedure and get pregnant fast? Thanks for reading
