Weight gain during pregnancy

This is my second pregnancy. I was 185 pre pregnancy. I’m 5 foot 11 tall, slightly on the bigger side… I’m down to 173 at 26 weeks pregnant and the doctors are making a huge deal on weight loss. They’re sending me for an extra ultrasound in a few weeks to check growth which I’m not complaining about as I get to see my baby and make sure she’s growing good but they really made me feel shitty as if I’m not providing my child with nutrients to grow properly. I eat healthy and I’m pretty active with 3 kids ages 3 4 and 5 so I’m busy to say the least. I’m a high risk pregnancy esp preeclampsia. I take my prenatals… I don’t understand why they are pushing my not gaining weight and diet on me when I told them multiple times I eat regularly and I eat good food.. it’s not like I’m starving myself and the baby lol
