Oh AF... why do you toy with me?

So I am officiallly one day late according to my longest cycle and still getting BFNs. I am on cycle day 36 and 16 days past ovulation. If I go by the longest of everything and throw my charting out for the month, the latest day that I have ovulated is CD23 and the longest luteal phase that I have had is 18 days. So adding those two together, a worst case scenario cycle for me would be 41 days long. That means that I'll give it until at least Monday before I start really freaking out that AF is a no show. Can I just tell you how much I hate being a girl right about now?
