I don't know, I've heard people say that PCOS is supposed to be painless, but I can tell you how I feel during the middle of my cycle. About two weeks before my period is do (that is before it stopped coming) I would get unbearable stabbing pains. Like the kind that make you scream out loud and fall over. I've always considered myself to have a high threshhold for pain, in fact I delivered my son with minimal pain and uncomfortability, and that was without the aid of any type of drugs at all. But when I get those cramps theres nothing that can be done except wait for them to stop which sometimes takes 5 minutes and sometimes takes over an hour. Even the painkillers they prescribed for me did little to stop it. Also, the week before my period was due I'd vomit almost every morning, a bit like morning sickness. Not very pleasant. I don't know if its normal, but thats the way it is/was.
