Rainbow baby needs help!

Emily • 22, Married to my love🌹Army Wife 💍 Angel mom of 7

We had a missed MC at almost 9 weeks that started on Oct. 10th, But the baby stopped growing at 5weeks and 5days. I'm now pregnant again (yes, it's a new pregnancy. My levels were confirmed at 0 a week or so before I took a test) and I'm waiting until Tuesday for my doctors appointment to get on Progesterone. I'm just super nervous that something might happen before then so I'm trying to give myself "bed rest" until then and taking alot of folic acid. any advice?
