Awkward growing body

Stephanie • 37 yo, EDD 11/14
I am a size 16, 5'9, and 35. I'm 13 weeks and I don't recognize my body! I've lost a few pounds since conceiving, but things just don't fit like they used to. I feel like I need new under wear, and new pants! But maternity pants are too big. Anyone else feel like their body is changing before any sign of a bump? Or feeling anything like this?!
