Why so different?

Things I do not remember happening to me last time I was pregnant:
- My hair is falling out...this did happen but not until after Gabby was born. I think it's time I rethink my hairstyle?
- I am hungry ALL the time!! I go to bed hungry wake up in the middle of the night to go pee and I'm hungry, wake up in the morning and I'm starving. I was not this hungry last time and is probably why I'm having my next problem...
- I am gaining weight like crazy!!! It's attacking my butt, thighs and I already have a belly pooch. How is this happening already I'm only three months into the nine month ordeal.
- I mentioned earlier about waking up in the middle of the night to go to the bathroom. What happened to my bladder that I can't hold it till the morning anymore. This did not happen last time until my belly was big and everything was pushing down on my bladder, why is it happening now. Every night between three and four I wake up..then I can't go back to sleep cause I'M SO HUNGRY and all I can think about is what am I going to make for breakfast.
- I'm tired tired tired. Oh wait this did happen to me before. But I think I'm even more tired cause chasing around a one and a half year old wears you out. But I love her so much especially around one o'clock when she takes a two hour nap...I know I wouldn't get those when baby #2 gets here!
-I was also pretty constipated a few weeks ago but the good Dr gave me something for that and I don't have that problem anymore PRAISE JESUS!
Well I think that's about it...it's so amazing to me how each pregnancy is so different all very well worth it though and I'm hopeful these thing will just get better as I'm getting into my second trimester. I'm off to have a bowl of cereal...thank goodness for special K.
