I’m sitting in the parking lot crying after my IUI was canceled

I just need to get this out.
I was doing an IUI cycle with CNY and this is the second time something like this has gone wrong for me with them.
I followed everything they told me to do. I came in when they scheduled me. I had an LH surge on Saturday and told them right away because I knew timing mattered.
They still had me come in on Monday, and when I got there I was told I had already ovulated and it was too late for the IUI.
Now I’m sitting in my car in the parking lot crying because I feel like I did everything right and still lost the cycle.
I just feel really done with this clinic right now.
The process to have a baby in this country is so hard omg.
