Weight Gain

I know it is obviously inevitable to gain weight during pregnancy. This is my first pregnancy and at 26 weeks 5 days ive gained a total of 23 lbs (I understand everyone is different). My doctor told me a max of 40 lbs would be OK. I know there are only a few months left but I feel like I'm gaining too rapidly and I'm not eating any more than I normally would. My question is, is this too much to be gaining? Is this normal? I'm having a girl and just feeling very self conscious when I should be feeling pregnant and glowing 😫...sorry just needed to vent to ladies who understand ❤
