My Behind is gone!! :( :(

Gwendolyn • I'm 28, hubby and I have our 5 year old baby girl and now expecting baby #2.. We are so excited!!!
I am 27 weeks and I just noticed in the mirror that I have lost my butt!! I was trying on my black yoga pants and noticed that I no longer have my little bouncy butt. Any one else experience this? I stopped working out the way I did. I only walk and yoga during pregnancy. Oh I hope I get it back 😐
