Rainbow baby, miscarriage scare!

Bev
Hey, i currently have two girls aged 5&3, i got pregnant year and sadly miscarried at 7+1 weeks although i didnt find out until 8 weeks at a scan where we were told no heart beat.
I am now 5 weeks pregnant and absolutely terrified! I started off with heavy bloating but now my symptoms have basically stopped, is this normal? Is it normal to have symptoms then suddenly stop?
With our angel baby my symptoms slowed down before stopping rather than a sudden stop.
I cannot go through another loss!
