Sperm count for IUI?

Carly
Hi ladies!
My wife and I recently had our first attempt at <a href="https://glowing.com/glow-fertility-program">IUI</a> July 27th, and unfortunately my period came all the same on August 10th :( I was really hoping for beginner's luck! But we are slated to try again later this month. My one concern is that after our donor sperm was washed, the count was only 4 million, which from what I understand is a bit low. Anyone else using donor sperm know what the count was for yours when you got pregnant? I'm in what I'm now calling the OTHER two week wait - waiting to ovulate so I can try again! So impatient.
