Okay so you're in the down reg part of your cycle and you still haven't O'ed. Okay, I now get what they aren't doing a BT until next Monday, because they just want to make sure you've O'ed and are in your luteal phase.

I don't know how the world works, but I am usually as regular as clockwork, and almost without fail, prior to a IVF cycle, I have a 'long' cycle where I don't O for ages. I don't know if it's the anticipation or the stress but it's like a trick our bodies like playing on us, just when the suspense is already unbearable, they drag it all out a little longer, just to torture us that little bit more!

Huge hugs, hun. I know the wait is a killer. I am sending loads of E2 vibes your way so that you can O already!
