I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> a week ago tomorrow and have been taking a nightly crinone (progesterone) insert for the past 5 nights. When I wiped today I noticed a little light spotting. Should I be concerned and assume that it didn’t work? I’m only on CD21 and it seems early for AF. My blood work to confirm pregnancy isn’t till the 21st. This is my 3rd <a href="https://glowing.com/glow-fertility-program">IUI</a> and this has never happened before!
