Abnormal AF after IUI

Ki

Hey,

My SO did our first round of <a href="https://glowing.com/glow-fertility-program">IUI</a> on April 3rd. I got the blood work done on April 17th, and started bleeding later that night. Of course, the hcg test was negative. I’m technically on CD 3 (the flow actually started the day after the blood test). However, I’m not bleeding like I usually do. It’s light and isn’t there all the time. Usually by day three I’d be just getting out of the heaviest days of my period, but I haven’t had any super heavy days yet. I’m wondering why is this? I’m not taking or doing anything different. Ideas?

Thanks!
