HORMONES!!! Friend or Foe?!

Ok so I have gone through my first round of Femara.  When taking the medication, days 3-7, I had no problems, no side effects or anything.  However... I am now on day 19 and this last week has been a loopy rollcoaster ride.  I can definitely tell a major change in my hormones!!!  I have been so irritable, and moody!!  I have had MAJOR cravings... mostly for mild buffalo wings.... bone in please. LOL.  Like almost every stinking day... and the good ole tender boobies, and even some nausea and vomiting.  I thought ok... with all of this going on it is such a tease and getting my hopes up!!  I know it is all just my hormones, but how in the world am I supposed to get a hint that I am pregnant when I have all this mess going on??  I have just randomly started crying over some of the most random things, and have been so sensitive and needy.  GAH!  I just have not been feeling myself AT ALL.  I am going on Saturday morning to get my bloodwork done to see if I have ovulated.  I have been doing the over the counter tests and so far they have all read negative.  I think I am going to be calling the DR. office and having a talk about getting an HCG shot and what the deal is with all that... All I can say is WOW!  This Femara is I-N-T-E-R-E-S-T-I-N-G!!!!!
