I was miserable the entire time I was pregnant. Not b/c I didn't want my baby but the first 3 months it was constant nausea. Then I gained so much weight for my frame it was hard to even walk around && my feet were always swollen to twice their normal size. && I carried him the last 2 months through the hottest part of the summer. I love my son, but I absolutely hated being pregnant.
You know the phrase, every pregnancy is different, it is 100% true!! Your hormones are different, thus causing a difference in your emotions. I am sorry that you are so down about life :( Just think about that little miracle swimming around in your belly and soon you will be able to look into their little eyes!!!
