Too much weight gain?

So I’m 27 weeks pregnant and I’ve gained 15 pounds. I want to only gain 25-30 pounds this pregnancy and I know I put on the most weight the last 10 weeks of my pregnancy due mostly to swelling (that’s how it was with my first) and I’m terrified that I’m gaining too much. I discussed it with my doctor and she isn’t concerned but I’m still feeling self conscious and worried about it.. it took me a while to lose the weight the first time and I just don’t want that struggle this time too
