Getting smaller

🍂Ash🍁 • My husband and I have 3 kids between us and just found out today (3/14/16) that after 2 yrs TTC we are pregnant!!
I feel like my bump is getting smaller. I've been losing weight this whole pregnancy which my doctor said is ok right now since I am overweight but I feel like my bump is shrinking too. The first picture (hair tie on my wrist) is 16 weeks. The other is today; 20w4d
