Weight gain..too much too fast?

Su

I had my 24 week appointment today. I’ve gained 12 pounds total from the beginning of my pregnancy but 8 of those in the past month from 20 weeks to 24.

When I asked about my weight the doctor said to be careful bc I should be gaining 2-3 pounds per month. The nurse even made a comment when she weighed me that I must have really enjoyed MDW.

I felt really good going into the appointment but now I just feel badly about gaining so much in one month. Has anyone had similar experiences, gaining a lot one month and then slowing down? Did you change your eating habits? Should I be concerned?
