I'm really confused. I'm 45, and had a tubal ligation 21 years ago. My period has always been like clockwork...28 day cycle, and only late 3 times before, with each of my pregancies. My period is now 14 days late...tender breasts, nausea, mild cramping, but no period. I took a hpt at 3 days late with a negative results. My question...should I be concerned about being pregnant or does this sound like the start of menopause. (A little background...I've been divorced about 4 years and have been with my fiance for 2 years. Definitely not trying to get pregnant, but we would be thrilled if it happened.)

Thoughts???
