Can't sleep post miscarriage

Catrina

So I miscarried at 9 weeks, had a d&c on Thursday, and it's now Monday morning. I've had terrible sleep since I found out I miscarried. But tonight was especially difficult. I don't think I slept for more than 20 minutes somewhere around 3am and then I woke up with a start like there had been a loud noise.

Is this from falling hcg?

How did you sleep after your miscarriage?
