Can I tell my gynae she's being rude?

I am 26 years old, overweight and pregnant currently in my 2nd trimester. During my visits to my private gynae at kkh, she often asks me to "lift up" my tummy so she can scan the baby. However, this request was uncommon with routine scans at the AMC. (Which I gather should mean that the machines can scan the baby irregardless of how much tummy fat one has.) She will also pass the same remarks like "your bmi very high" for every single visit (like I need a reminder) and repeatedly told me that I am only allowed to put on 5-9kg throughout the entire pregnancy. This caused me alot of stress and so far during the first trimester I managed to maintain the same weight by not eating so much. Whenever she makes these remarks it makes me feel very humiliated as she will have several nurses in the room at a time. Is it possible to tell her off that it's rude or should i just keep brushing it off as a need for every check up? Does anyone else face something similar? My friend who's also overweight during pregnancy told me her gynae passed off several hurtful remarks about her being overweight too, so I guess it's normal amongst doctors to bash fat pregnant people. #pleasehelp
