Pregnancy anxiety?

So I’m 5 weeks pregnant today according to all the tests I’ve taken. I found out last week, and still have the urge to take a test every morning just to make sure it hasn’t gone away 😅 does anyone else have this problem? We’ve tried so long for a baby and now that it’s happening, I’m so worried about it being a chemical pregnancy or something of the sort, and it not being real. My first appointment isn’t until the 16th so the wait is making it so much worse.
