I skipped a few pills So now I have had no period...

Hi, I have been on Loseasonique for over a year, but I skipped a few pills (not consecutively) during Sept '11 (esp when I suspected pregnancy). It's hard to date when I possibly conceived, but I had weird feelings in my uterus after having unprotected sex 2x around 9/23 & some slight spotting. Now it's 10/15, & I am 7 days late for my period (this past week was when I was supposed to get a quarterly period). Normally when I don't take hormone pills during my period week, I bleed. So now I have had no period, have had slight cramping that feels milder than period cramps, I have had headaches, my chest and face are flushed (have been flushed for 3 wks now), I have a backache, I have vivid bluish veins appearing on my chest, arms, thighs, and abdomen, my nipples are darker, and I have been exhausted after doing normal activities for about 3 wks. However, I keep getting negative HPTs. Could my two, small uterine fibroids be causing these symtoms? Should I keep taking BCPs tomorrow?
