Pregnant and one of the only symptoms I have had went away.

I found out I was pregnant 5 weeks ago. And those past 5 weeks I don't have any symptoms besides for just sore breast and i hate the way the food smells of my husband cooking. I really dont feel pregnant and sometimes wonder if i actually am pregnant

But i had taken multiple positive test and had my ultrasound at 7 weeks and 3 days and they said baby had strong beart beat.

I am now 9 weeks and 2 days pregnant and the past couple days I have not felt any sore breast at all. Is that something to worry about or is it normal for it to go away? Without sore breast I don't feel anything at all and makes me worry maybe something happened this week.
