Only gained 3 pounds at 19 weeks

So I am currently 19 weeks pregnant and have only gained 3 pounds so far. I am hoping I don’t pack on the pounds as I get further along. My first pregnancy I gained 65 pounds total and 17 of those pounds were in the first trimester alone 😳😳. ( and only lost about half of it so I started this pregnancy much heavier than I should be) I am really hoping I actually only gain 25 pounds this pregnancy in total and I don’t all of a sudden start gaining crazy amounts of weight in the last trimester.

Can any tell me if they gained weight slowly at first but then gained weight quickly toward the end? Or does it sound like I am on track to stay around the 25 pound weight gain?
