Doctor forgot the progesterone test?

I went in at 6 weeks and got blood work done. She ran a bunch of tests but forgot progesterone. When I called and asked they were like oops yea come back and we will test your levels. My best friend and husband think it's a huge mistake and we should look for a different doctor. Is it that big of a misstep? I go back at 8 weeks for a sonogram. I am going to try to get blood done before that.
