I was on Nuvaring for 3 months, and had not tried BC before. Due to total lack of libido and some irritation I decided not to put a new one in after my last period (which started Sept 6). My cycle before Nuvaring was 23 days, but occassionally would be longer.

I thought I felt my period coming (slight cramping) and had unprotected sex on Sept 27. It has now been 31 days since my last period and 11 days since we had the unprotected sex. I have been cramping for over a week and had very slight spotting last week. Also some lower back pain. It feels like PMS.

What do you think? Another key factor is that I am 43 (and have never been pregnant).
