Asked earlier, but maybe it didn't compute?... any input here...?

I'm on Yaz strictly for PMDD, began taking it last October. Normally my period comes around Fri/Sat/Sun, when I begin a new pill pack on Sundays.
My period never came when it was due. I'm technically 8 days late. No, there is no chance of pregnancy, since I had the Essure procedure done back in 12/04.
I've been having menstrual type cramping for a few days now, sometimes rather severely. However, there hasn't been any bleeding at all. I do have a hx of fibroids and polyps, and I do know that there is a small fibroid currently. I also have ovarian cysts, and have been feeling pains in my left ovary almost consistently.
I had an ablation done in 12/04, it lightened up my periods. Taking Yaz made the periods even lighter. I'll be 40 in Jan. Should I just chalk this up to possibly a perimenopause thing? I had symptoms of peri when I was 36, nothing too severe, mainly hot flashes.
Is this a reason to call my gyn, or do I just wait it out, see what happens next month?

Thanks. :) I wasn't going to repost it, but I figured, what the heck.
I had left a msg for a nurse to call about this last Wed, nobody ever returned my call. I'm considering making a gyn change, have made a couple of calls today to gyn offices in the area. This isn't the first time this has happened, with phone calls not being returned. I went through it in May, had to call 5 times in 3 weeks before getting a response.
The joys of being a woman... LOL...
Thank you.

I would definitely contact the gyn to be sure in case it is not that and something else you can catch it early...it sounds like peri to me but I am not an gyn I would at least call a nurse helpline to go over symptoms just to be sure of the possibilities...

When in doubt, call the doctor. That is what they went to school for.
