Fluctuating symptoms

So, I found out I was pregnant on the 12th July because I was feeling sick, I’ve had my booking and have a scan on Friday. But my sickness has suddenly gone. My breast tenderness seems to come and go.

This is baby number 4 and I wasn’t sick at all the others but had breast tenderness.

I’ve had 3 ectopic pregnancies the last one resulting in my tube being removed, so I’m worried. Am i worrying too much ? Am I thinking too much ? Helppp
