Well guess what, AF got me yesterday too, so my CD1 was yesterday. I would say your CD1 would be yesterday, because that was the day of full flow.
I know how you are feeling, I am feeling sad too, but I'm better today. I already called RE and my u/s is not until Aug 6, so I have to take BC pills until then so then we can do IUI #3
So LOTS of luck to you this cycle!!!
