Question about PCOS...

Any mom who have Pcos
I do have a question!! 
Does your doctor ever tell you that it cause from your weight?  
👉well my doctor told me the reason why I haven't had my period since June 2014 is because of my weight.  But I don't know if I am only one who have been told that!  
Today I just finally started my period. Plus my husband and I are trying for another child.
