Emotional after ceasing BC

Let me start by saying- I am not an emotional person. Over the past year I may have cried twice and once involved anesthesia, so I almost don't even count it lol. I went off birth control in December. Since then, it seems like I cry at the drop of a hat. I get emotional over TV shows, cry more because crying is making my nose run (seriously- I cried over this...), my dogs... It also doesn't really matter where I am in my cycle, but it's obviously worse when I'm PMSing. Is this normal??
