10wks 4days and symptoms going away?

This is my first pregnancy, my symptoms have all pretty much subsided.. I still get a little nauseas, and am still tired, but vomiting, sore breasts and peeing all the time has pretty much disappeared.  I am getting worried that something bad has happened. I have booked a doc appointment but just wondering if this has happend to anyone else and if it has was your baby still healthy??? Help :/
