Crazy Hormones

Recently, I have been a complete mess when it comes to my emotions. All of these pregnancy hormones have been making me cry every ten minutes. It has gotten so bad that I even started crying after hearing an OnStar commercial on the radio. Nowadays, I can start crying for no reason at all. I'll feel all of the emotions of sadness, but have no idea why I'm crying.

Has anyone else ever had this happen while pregnant?
