Natural fet - timeline?

If anyone has gone through a natural fet (no drugs) would you mind setting out the timeline of tests you’ve had to do prior to the transfer? Are there any complications or potential reasons for cancellation that your RE has mentioned? I’ve waited 2 periods post egg retrieval (due to hyperstimulation) and we have chosen to do a natural route. We did not expect this wait, so for our first fet I want to make sure I’m well aware of any potential disappointments!!

For me so far:

Cd3 - ultrasound, cleared to go ahead

Cd9 - blood test

Thank you!
