Bad doctors appointment

I'm 18 weeks today and had my monthly doctors appointment. I gained 10lbs in the last month (11lbs total gained this pregnancy) and my doctor got on my case majorly about the weight gain. She's not happy with how much I have put on and keeps reiterating that I'm only allowed to gain 25lbs ( I started off at a healthy/normal weight and BMI so I wasn't too big to start out with) so I left her office in tears (exactly what happened my last pregnancy too except for I started off that one 10lbs heavier and gained more weight by this point then than I have this time around). I hate feeing like I need to cut calories, especially since the majority of my diet is fruits and veggies. I rarely eat sweets, don't drink pop, and don't pig out. I eat when I'm hungry and my portion sizes are generally smaller than they were prepregnancy. I'm feeing so down and since I have had a history of eating disorders, I feel like I need to restrict now.... I'm majorly stressing...
