Can’t get prescribed clomid

I am overweight. 5’5 245 pounds. One healthy 2 year old who I had when I was about the same weight. I am having trouble getting pregnant so I saw a new OB/GYN as mine moved out of town and he said I was not ovulating. He owns a medi weight loss clinic and told me I had to lose weight before he would help me try to conceive. I just asked again as I have lost about 15 pounds and this is the message his nurse sent. What the crap. My previous OB never commented on my weight. Do you think he is just trying to get me to join his weight loss clinic so he can get double my money?? The weight loss clinic costs me 70 a week which I cannot do.
