Thanks Jasmine and Bunnyfeet. So far I spoke to the IVF nurse based at my clinic (not the IVF nurse that is assigned to my FS) and she said that the reason why the first AF after the medicated cycle is skipped is because the meds mess up the cycle and that's why they wait for the next AF. I was waiting for the call from my IVF nurse form the FS's office today but it didn't come, I just wanted to ask her what went wrong. I'm sure it will be something along the lines of 'the meds just didn't work, we don't know why lada lada lada'.
