Sickness getting better- but I'm concerned!

I started with morning sickness around 5 weeks and it has increased gradually since then. I am 7 weeks today and today and yesterday it has been some better. Still with some nausea in waves but it's not constant like it has been.  I am so nervous about a miscarriage. No bleeding or cramping. Am I just over analyzing or should I be concerned?
