I can relate to the bitchyness and I am usually a very patient person, but man I just want to be left alone lately. I knew I was pregnant because of the bone tiredness..I'm usually tired but I was falling asleep sitting up during the day so I knew something was up. Also getting out of breath at the slightest exertion. Both of those seem to have passed for the most part. Now it is random waves of nausea and smelling everything and food aversions that change from day to day. But overall my symptoms are mild enough that I worry..but just keep telling myself to enjoy an easy pregnancy while it lasts because tomorrow I may wake up sick as a dog.
