Feeling like CRAP ???

Soooo since yesterday I've been feeling like major CRAP!!! I can't place what it is I'm feeling. I do know baby boy is laying on my intestines so that's part of my problem along with not having proper hydration with water. I feel like a blimp....because the size I was a week ago is what I was full term with Baby Boy #1 and now I just keep growing!!!! It's all so different for me. I love how it looks but the feeling is NOT FUN one bit!!!!
