Hello,I'm 23 and I'm getting ready to go my doctor on July 11th to be checked for PCOS,because I have extremly irregular periods,anyway,I was curious if you could still have the syndrome despite having absolutely none of the other symptoms? I have been overweight most of my life and just recently I have lost 80 pounds in five months,I was wondering if my bizarre periods could be caused by a lack of nutrition? I am also clinically depressed and I was wondering if that was a factor
