Pregnancy weight gain

I’m almost 25 weeks and have gained 18lbs 😩 I’m so scared but I was so sick the first 3 months that once I started feeling better and could eat I’ve been eating normal cant say I’ve been overeating. Could be just water weight on top of regular weight gain..my boobs are heavier to and my butt looks bigger and my hips. How much weight have you ladies gained so far? And I still have another 15 weeks or so to go 😬 will start walking daily after dinner hopefully that will help me feel better at least.
