Is AF playing Mind Games, am I PREGGO or not

Ladies I need your advice. I had 2 polyps removed in July. Had a cycle in August, nothing in September and last cycle was Oct 6th lasted 5 dys which is normal, which was also my first month using the Fertility Monitor. The Monitior said that for 15 days straight after my first test that I was at High Fertility. So DH and I BD. The monitor says I'm on cycle day 47 and no cycle as of yet. Besides missing the one cycle for September (which I think was due to extreme stress with losing a family member) My cycles don't normally skip months. Although they are irregular and normally come between 32 and 35 days I still manange to get one every month. I don't have alot of symptoms except for my nipples are sensitive which is kinda a sign that my cycle is coming, which have since subsided, but that stay erect (DH always ask am I cold, LOL) I was having sharp pains on my side which may have been the big "O" but that has subsided, back pain which is normally but other than that nothing. I'm trying not to get my hopes up but the missing cycle is puzzling me. Other than the nipple tenderson i'm not experiencing and other PMS systoms, so what do you guys think. Oh GYN appt is in DEC in case that was your response. :)
