Do I Have PCOS(Polycystic ovarian syndrome)?

It doesnt sound like you have it at all. You would most likely have abdominal pain from the cysts as well as many other symptoms if you had PCOS. It's really easy to read a list of symptoms on the internet and then relate it to yourself and think that you have the condition, but generally you would be quite aware that something was really wrong if you had it. If you have any abnormal symptoms let your doctor know so that they can work out if anything is wrong.
