Maybe First Movement

Danielle • Mommy to a precious little boy born 12/17/15 and full time working mom! I love my little family!
As I'm sitting at my desk, typing away, I feel this strange sensation in my lower stomach, like when you're cold and get cold chills and start to shiver. It lasted a couple seconds and stopped. I've had gas during pregnancy and that was definitely not gas. Could it be me feeling my little one moving around for the first time? I'm 17 weeks.
