Fear of the first appointment ?

I am fearing my first appointment this coming up Wednesday to confirm my pregnancy. I have no clue why im so scared But I’m terrified I keep telling myself it’s okay, I’m okay, the baby is okay. I’m the person who takes 50 million pregnancy tests to make sure my line is progressing. Has or did anyone else have this fear? I have pretty obvious positives but I’m still terrified of all the outcomes and I tend to overthink and get anxiety over this stuff. Someone help with words of encouragement....
