BBT after IUI

Ashley

I am currently 5 dp my first <a href="https://glowing.com/glow-fertility-program">IUI</a>. I normally keep track of my BBT post ovulation but I'm wondering how many of you do and if I should let it go (until hopefully my BFP). The last two days my BBT has decreased slightly and is (according to one app I use) only 0.02 above my coverline. I find this dicouraging, so should I stop?
