Hi ladies, can I join you?

I had a blasto FET on the 11th. I was due for a visit from AF yesterday and feeling uber confused because on the last 5 fertility treatments she arrived on the 17th of the month, even with Crinone. Now it's the 18th and I'm feeling a bit menstrual (unusal for me with no actual AF). Also caved and got a BFN on the POAS on Saturday morning.

Going completely insane and I can't believe I still have to wait a whole week more (BT 25th)

Sounds like I'm not alone in this insanity. God this is torture!
