Feeling hungry

Hi I am almost 9 weeks pregnant and have been hungry all the time. I don’t want to gain so much weight in first trimester but if I don’t eat, I get sick. So I eat. With my son, I was feeling sick till 20 weeks so I lost weight. Still I gained almost 30 pounds. Then I had hard time losing all of the weight so I really want to control my weight this time and just don’t want to gain so much. Does anyone else feels like this way? Being hungry all the time? Any tips to control that? Thank you!
