Period after egg retrieval

A

Hi.

I had my egg retrieval on Friday. We’re doing PGS testing so waiting until September for a FET. They told me I would get my period anywhere from 2-14.

How long did it take you ladies to get your period after retrieval?

I woke up this morning, and I really feel like it’s coming. But we don’t even have day 5 blastocyst numbers and they told us it would take 2 weeks for the PGS testing. So if I do start early, will it mess up the transfer timeline??
