Hard time with weight.. 😫

So I'm barely 12 weeks and I've gained 12lbs. I'm normally 104lbs. I keep gaining and it's making me depressed. I'm already up to 116lbs. I should've only gained 2lbs in the entire 1st trimester. Why is this happening!!! 😫😫😫 I only gained 25lbs in my first pregnancy. I'm not liking where this is going. 😟
