Hello Missmochi, yes it is very common to have irregular periods when a PCOS diagnosis. I sometimes don't get mine for 3-4 months. If this is happening to you, it's important to check up with your doctor. It's important that your uterus sheds it's lining (a period) atleast 3 times a year. This can increase risk for cancer and disease if you don't shed the lining. Also, they usually don't remove cysts unless they are quite large or there's many, many tiny ones. Good luck with everything...
