AF iminent

So much for feeling good.  Hormones are really cruel.  I am having what I assume is PMS, I am a total grump and even though my temps haven't dropped yet, I am pretty sure AF is coming soon.  My temps don't seem high enough for me to be pregnant and don't really have any symptoms.  Hopefully I will know for sure by Thursday (which is my birthday).  I can't stand waiting and uncertainty.  Oh yeah, headaches/minor migraines not helping either. Grrr.
