Thanks for all of the good thoughts, ladies! I am going to wait (or at least, try to wait) and test in a few days again. Fingers crossed!
I think I should have a glass of wine, per @wifeofadam's suggestion. So freaking excited that I can tag you now, by the way! (Before I was always trying to make sure I got the "+" symbols in the right place, but alas, to no avail. )
I should have added earlier that I didn't use FMU for any of the tests I took today. I am going to try to wait until Thursday, and if I don't have AF then, I will test. I have got to calm down y'all.
