fat and wanting fertility treatment

Ughhh so I went to the doctor today for all my testing, well first round of tests. Had blood work done and an ultrasound done on cervix and tubes, everything looked great! She saw lots of follicles and saw that I DID ovulate last month. Well, she put SO much emphasis on my weight! Like it was all she talked about and was kinda rude about it. I know I'm overweight, but she made it seem as if I would not lose weight she wouldn't want to help me cause of possible birth defects and was asking like what do you plan on doing about it? Who's going to help you lose weight? Can you be denied and told we won't help you?!??!! I mean is that ethical? I feel so shitty about it😔😔😔. I'm 5'6 275 but was 330 at my highest and have made some headway. Comments from larger woman who have had infertility please! I don't know how to feel 😞😞🖕🏻
