I forgot to mention the strongest and most noticeable pregnancy symptom that I have these days: My raging hormones.
In addition to the crying, I have rapid irrational mood swings. I can go from elated to severely pissed off in about 2 seconds. It doesn't take much. The longer I am left to stew about something, the angrier I get. This includes things that I have been angry about and have had resolved. I also manage to come up with illogical rationalizations for my anger and can direct it upon anyone.
Last night I was angry at Ben for something that happened about a week ago. I wasn't mad about it at the time, but yesterday I decided I was mad about it. When I told him about it, I started to cry. I wasn't mad anymore, now my feelings were hurt. And then I yelled at the cat about what an a$$hole he was being that day. This all took place in about 10 minutes. And then I was fine. Ben and the cat are also recovering.
