Day 42 of cycle, no PMS symptoms (PCOS)?

Hi all, Apparently I have very, very mild PCOS and have had it for years. My periods were only regular at one point in my life coming every 28-30 days. For the last 3 years, prob due to an array of small factors, my period seems to come anywhere between every 38-43 days. The thing is, I usually have PMS symptoms at least a week before. Right now I am on day 42 and really can't say I have any PMS symptoms. This is pretty late in my cycle, so I would probably have them by now. Has anyone else experienced this? I doubt I'm pregnant and would be SHOCKED. Esp. since I really have no symptoms.
