17w and gained 20 pounds - stressed about weight gain

Putting the flair as rant since I’m not sure what else to do. I am feeling so stressed about already gaining 20 pounds fairly early in my pregnancy and I know there is more weight gain to come. I’m eating healthy foods, my problem is I’m just hungry all the time.

Pre-pregnancy I was 135 (I’m 5’5”) and this morning I weighed myself and I’m 158. For those who have been pregnant before - do I have any chance of the weight gain slowing down in the second and third trimesters? Trying to stop spiraling over here.
