Should I be worried 😫😫😫😫

Alyssa
Okay this is my second pregnancy , my first one was a healthy pregnancy until at week 20 my baby's heart had stopped beating so of course with this pregnancy I'm super worried !Β 
I've had so many symptoms , this time since week 6 and the past to days Ive had none at all should I be worried I go weekly for blood work and everything is great they say , but I don't have an ultra sound for 6 more days ! What should I do ?!
