My doctor said I’m to young to help me with ttc

Hi ladies

So me and my husband have been trying for 15 months with no luck, went to see a doctor a month ago and got diagnosed with pcos so I’m not ovulating. She gave me metformin which this month didn’t work for me. So i went back today and she told me that she couldn’t do anything else for me because I’m “young” she told me to keep taking metformin cuz they would not give me something else because im too young (btw i just turned 20) so my question is, is she right? Are all doctors gonna tell me same thing?? I was so hopeful to see a doctor because i really thought they could help me but now I’m feeling so down😞
