Need help understanding IVF timeline!

AT

Can someone help me understand this schedule? My doctor drew this for me as a rough outline of the process. I think I understand through stims / egg retrieval ...

Then I go back on birth control? For how long?

What is EPs?

When does genetic testing happen?

How long do PIO shots last? And this is progesterone right?

We’re doing PGT-A and frozen transfer if that helps.
