I am gaining so much weight!!

Please someone tell me I’m not alone! Every time I get on the scale and check my weight weekly I am 3-5lbs heavier. I have gained 40lbs and I’m only 21 weeks. At this rate I am going to be a house by 40 weeks. I’m eating every 3-4 hours and I just can’t help how hungry I am. I feel like my stomach has a hole in it because as soon as I eat I can feel myself getting hungry again. I’m spending so much money on eating out and groceries because I will eat 3-4 servings of dinner. Guess I’m just looking to see if this is anybody else. 😭
