Gaining too much weight? 😫

An
I'm 24 weeks and have gained 13 lbs. I'm worried about putting on too much! My doctor said my ideal weight gain would be between 15-25lbs, which means I can only put on 12 more!! 😩😩
 
Is it true you put on most weight in the third trimester? How much did you gain, if you don't mind sharing??Â
