I know in the first trimester of the first pregnancy I was pretty nauseated and super sleepy. I'm definitely tired and I had some nausea during the weekend of implantation. I know it was implantation because I had all the other symptoms, plus a fever, chills, aches and vomiting. So yeah...that is how I knew I was pregnant.
I've read that the second pregnancy is more relaxing since the mom already knows how to deal. Well, I'd have to agree with that. I know my mind is not 100% consumed by pregnancy thoughts (yet). I actually am not really sure a baby is in there (well an embryo at this point). I definitely can't button my skinny jeans but other than that- I have a symptomless second pregnancy.
Come on heartburn! I want a girl!
