Weight gain/loss in first trimester

Just wondering your experiences with your weight during pregnancy, I'm 150lbs at 5'3 so certainly not underweight by anyone's terms, but at 9w I've lost 7lbs. With my first I'd put on 10lbs by this point. Not had horrific nausea or anything but definitely lose my appetite from time to time. Will I probably start gaining from 2nd trimester when my hormones settle?
