Barely and symptoms and overthinking

I think it is because of my past experience with my first pregnancy that ended up in a miscarriage that I'm overthinking everything with this one... I'm currently 11 weeks and 2 days and I haven't experienced anything wrong with the pregnancy, but this past few days I'm barely having any symptoms. 
I'm hoping and praying that everything is going good and that baby is growing and is healthy. 
I'm having my next ultrasound at 13 weeks and 1 day... time cannot go fast enough for that day to be here.
