2nd retrieval

Hey you all. I am new to this whole IVF thing. I had my first stims and retrieval in July. For those of you that had a second stims and retrieval did you do it the following month? Like would I do it in August? And does it cost the same amount as the first one?

I was thinking let my body rest because back to back surgery seems kind of alot and also iam waiting for PGT-A testing results before I decide on what to do from the first retrieval which the results won't come back until mid August. So it looks like I won't have a retrieval until September. My ERA In October and I guess transfer in November? Am I calculating everything correctly?
