Weight gain

FTM here. I just had a doc appointment this previous Monday and my doc said my weight gain is ok, but I still worry. I was 204-206 lbs before getting pregnant and now at 21 weeks I'm sitting between 227-230 lbs. According to online I was obese before getting pregnant so I shouldn't gain more than 17lbs but to me that seems unrealistic. Especially knowing I am already at 20-25 lbs. I occasionally splurge and eat something sweet but for the most part I try to stick to a consistent diet. My morning is scrambled eggs and 2 slices of multi grain toast. My snacks throughout the day is a package of belvita crackers, 1-2 bananas, and a string cheese. Lunch is usually a lean cusine meal. And dinner is some form of meat and veggies.

Should I be worried about my weight gain? I am only 21 weeks so i know I have a while to go and I feel like 25lbs is a lot but I also don't want to stress over losing weight now since I can't imagine that is healthy for the baby.
