Weight gain

When I went to my doctor 2 weeks ago and they gave me a summary paper from my visit it showed my weight and I’ve noticed I’m up 17lbs from my pre pregnancy weight. Every visit I’ve gone to my doctor has not mentioned anything about my weight. But I am worrying about it. It’s not like I eat particularly bad, so idk why I’m so worried. But I also hopped on the scale this morning and noticed I’m up 4lbs in 2 weeks! Am I just overreacting? I’m 26 weeks today.
