Help Please Ladies...

So I am 6 weeks pregnant, extremely happy and excited. I am a little concerned though because I haven't had any symptoms outside cramps here or there. I'm loving any and all food, going to the bathroom (peeing) a lot but outside of that no symptoms. 
I had a miscarriage last year, and I'm a little worried/nervous. Is it okay to not have any symptoms or the very few that I have?
