Crying over peanut butter?


So, I'm about 6 weeks preggers, and I realized yesterday how much I have been complaining about everything latley! I'm hungry every hour of the day it seems, I'm crying about really dumb things, and I have been waking up at 4am! All it takes is something as simple as not having the right kind of peanut butter and I start bawling! I'm not picky it really doesn't matter to me but, if I have a day I want crunchy and all I have is creamy I'll My first pregnancy wasn't like this, why am I crying over peanut butter? lol
