Possible miscarriage

I went in to verify the pregnancy today and the PA said that I’m either off on the dates or that it’s a miscarriage. They are monitoring my HCG levels and then bringing me in for a rescan next week.

I was in the ICU earlier this year and we had been hoping that this would be our rainbow for the year. I’m feeling so many things - I’m devastated. And terrified of the thought of a D&C In a hospital or potential complications of a miscarriage. Any advice?
