Should I be worried??

I'm 10weeks and 1 day (first pregnancy) and today is the only day where I haven't felt sick. Ever since I found out I was pregnant I've been sick with something. Nausea, dizziness, fever, headaches, cramping, sore breasts, bloating, you name it I've had it. Today I woke up with nothing. Nipples are a little tender but not to extent of what they were before. I'm a little nervous as I have been having some outside issues that I put a lot of stress on me (work and family life). Is it normal for symptoms to taper off at 10 weeks or is something wrong with the baby?
