5dp5dt update

I am 5dp5dt (5 days past 5 day transfer) today and am surprised at how easily I've been able to resist testing. Cramps did come back for me last night with some pretty noticeable pinches and boobs are slightly tender. But all can be explained by progesterone I guess. I am wondering when the Aunt Flow typically arrives in an IVF cycle if it fails? After progesterone support stops or does it just come when it usually comes? Well, time will tell - hopefully my period will just stay away for 9 months!
