Mother Nature is a tease *Update*

My period is three days late.  My period is never late.  The latest it's ever been was two days and even then, the flow started to happen the evening of the second day.  Here I am on day three, and still no spotting.  I've been having mild cramping on and off over the past week.  Even with my IVF cycle, even with all the medications I was on, my period arrived on time, 5 days before my beta appointment.  I'm trying not to get excited, because I've been so disappointed in the past.  I honestly don't think I'm pregnant, but of course I hope I am.  My husband has been out of town for the past week for work, and I haven't informed him of AF being MIA.  Not only does he need to focus on his work, but I don't want to get him too excited, only to be disappointed if AF arrives.  Also, I've avoided home pregnancy tests because I don't want to be crushed.  In my odd way of thinking, POAS would mean that I think there's an actual chance that I'm pregnant.  Like I would be jinxing it and then it would never happen. Surely this evening, AF will arrive; I'll allow myself a little cry and mourn the loss of yet another cycle.  But for now, I would like to remain in this moment of possibilities of "if" for a little longer.

If this natural cycle is a bust, I start my FET cycle.  I've got the Estradot and Crinone ready to go.  Here's hoping that I won't be needing them.    

**Update**
Still no AF.  Five days late.  I took two cheapy HPT this morning = BFN.  I've been reading up on it on fertility boards and this appears to be pretty routine.  Most women, after an IVF cycle, are late for their second cycle.  One poster mentioned that AF is typically 7 days to two weeks late.  Ugh!  Tomorrow I will be calling my RE's office to find out what I should be doing.  Do I start the meds?  Do I wait until AF?  I just want to get started with this cycle.
