Second pregnancy - more fat deposited?

Jane
I'm just starting the third trimester of my second pregnancy (son is 18 months old) and I feel like my body has laid down more fat on my hips, lower back, thighs, and butt compared to last time.... Though my weight gain so far is only 1-2 lbs more than last time. 
Has anyone else noticed this? So nervous it's going to be tough to lose, too!!
