Counting calories while in first trimester

I'm 10 weeks now and I have been eating 1400-1750 calories a day. I'm 216 pounds now and started at 218 when first pregnant, is this a good caloric intake? I am not allowed to gain more than 11 pounds, I am young and am very self conscious. Thank you for the replies I did speak with my doctor she said as long as I'm not hungry I'm fine, and I was looking for advice not judgement
