Betania on "FET question - no period, & baseline E2"

Hope someone can shed some light...

Getting ready for a FET. Last bcp was last Sunday. Calendar said to expect period on Wed or Thurs. No period still.

I was scheduled for baseline E2 Friday. Asked my clinic if I should still have it with no period, did not get an answer before I left for lab, so I did have it. Do not know the results of the E2 but still no period. I feel like she is coming... have for days...

On Mar 13 had a fluid u/s. All is clear and lining was 7.

Has anyone ever experienced this?

And does anyone know what they are looking for in a baseline E2 for a FET?
Does my period not having started mess that up?

Thanks for any experiences you have!
