Baby bump already?!

Emily • Married. 5 year old son. 2 year old daughter. Pregnant with our last.
According to Glow I am 4 weeks and 1 day. I am 5'2" and about 115 lbs. This is my second baby so I knew I would show quickly but holy cow! Lol I'm thinking I may have multiples or maybe I'm further along?!
