Help! Needing positive vibes!

So my first pregnancy was a missed miscarriage at 8w3d. My only symptom for a miscarriage was the fact that all my symptoms disappeared.

This pregnancy I had symptoms a little last week (7 weeks) and the week before (6 weeks) but the symptoms have been gone completely for over a week and I'm freaking out. We go in on Friday to check via ultrasound but fearing another mmc.

Has this happened to anyone where the baby ended up being totally fine, even though you didn't feel pregnant?
