Concerned about Weight Gain

Ok , so I'm a FTM about 27 wks 2days . My last doctors appointment was two weeks ago when I was 25 wks. When I weighed in I was told i gained 12 pounds . Now , I had a super rough 1st Trimester and lost a lot of weight , so technically during my entire pregnancy I've gained only 11 pounds. My doctor said " ideally " im on track but I need watch my weight gain . But the nurse that weighed me was kinda rude about the whole thing . After I jokingly told her I spent a few days at my grannies house around Easter , and it was her life's mission to fatten me up she responded " Well you don't need to go to your grandmother's anymore with the path youre going ." In the most snarky rude tone . I guess I'm just upset because at first they were really hard on me about the fact that I needed to gain weight , so when I finally pick up an appetite Im told Im gaining too much . Ugh !!! Any moms out there with helpful advice or similar situation ?
