Getting bigger

Im 25 wks and 3 days today. I've gained about 16-17lbs and the scale just keeps creeping up and up not matter how much i watch what i eat. I dont want to constantly worry about food and my weight, i want to enjoy this pregnancy but i feel like thats all i do. I dont have a great metabolism and before getting pregnant i was always counting calories to either lose or maintain my weight. I dont want to gain more than 30lbs this time and im feeling like that is going to be impossible as im getting closer to my third trimester. Anyone else feeling discouraged about how they look/what the scale says?
