I had EC last month and found EC (egg collection) to be fine. No problem while during the procedure. The drugs they gave me knocked me out. I felt completely fine. Once I was home, I was drained and really tired. The next day I went to a friends house for a BBQ and i dont remember any pain.
However, I did find ET (egg transfer) uncomfortable and embarrasing. Once it was done, i wasnt in much pain. I found the trigger shot to be painful, and just the constant bloating really uncomfortable and I was walking really slowly.
I am sure you will be fine.
