Sperm Number?

Options
Hi everyone! I had my first IUI this week.
The first day, my sperm count was only 5 million - motility (or whatever its called??) was 9.6 - The second day (I did back to back) the count was 20 million and the motility went up as well -
I emailed fairfax and they said they guarantee 10 million - Mine was ICI but my clinic rewashed it - Fairfax said the guarantee is 10 million. Has anyone had low numbers happen? What does that mean? Did Fairfax refund you or give you another vial? TIA.
