Ovarian cyst

Ok so I have 3 ovarian cysts 2 on my left and 1 on my right.. My doctor say it's normal for my age because of spike in my hormones. That's beside the point though. My problem is that I am now 9 days late on my period .. I've never been this late before 3 days tops. I've read online that ovarian cyst can cause your period to belayed or missed. Could I be pregnant or just my ovarian cyst causing my delayed period. Oh yeah I've been having heat flashes too but they just started like a couple days ago.
