Emotional roller coaster

Does everyone experience this? For everyone who know me, they know that I NEVER cry. Really, I don't. I can probably count the times I have really cried on one hand (before I got pregnant that is) now it would probably only take a week or two to fill up one hand. Seriously I can't believe how much I have cried lately. And it's usually over dumb things. For example, one time my sister-in-law called me and left a message on my phone and when I listened to it, she said that she had just left the gym and was just calling me to chat. Well we used to go to the gym together all the time and for some reason I just lost it. I bawled and bawled! Wes just laughed at me (after he consoled me of course) and he was saying, "you don't cry like that when I leave you messages". It's not that I was really sad although I do miss going to the gym with Aubrie, it's just sometimes I get this overwhelming feeling to cry. My emotions are all over the place, Wes said this is also an emotional roller coaster for him too because he doesn't know what to do with my always changing emotions. The other symptoms I was expecting, the swollen feet after standing all day, the heart burn after every meal and of course, the growing tummy. I just wasn't ready to cry all the time.
