PCOS??

Ok so I had blood work done because my cycle is extremely irregular. Well everything came back normal except my LH is a little high? My LH Is 15.2 while my FHS is 6.1. Does this mean that I definitely have PCOS? Also I read the people with PCOS are normally larger in weight. I’m 5’5 and 124. Does this mean that I am going to gain weight? I’m just so confused and I don’t really know what this means for me. I have an appointment to go over my blood work this week but I’m just extremely nervous. Any help and insight would be much appreciated
