Weight gain frustration

So my entire pregnancy I have been very worried about gaining to much weight(I gained 75lbs with my first 😳) this pregnancy I have been much better about eating healthy portions and not eating much junk food. I have always had a hard time (mentally) gaining weight and am finding it really difficult now even while pregnant. I am just about 26 weeks and have gained just over 20 lbs. Can anyone else relate? How much weight have you gained? How active are you?
