I had a tubal on my oldest dd's 21st birthday - my littlest one had just turned a year old. About a year after my tubal I skipped a month and felt some of the same symptoms as when I was pregant (never had morning sickness with 5 pregnancies, but the tiredness, sore breasts, etc.). I few weeks later, I had a gush of water - I thought I had peed my pants for a second. I'm thinking it was an early miscarriage. I started my period a couple of weeks later. I have been careful about avoiding ovulation time since -- I'm 43 and dh is 46 and we are defininitely not wanting more children at this point in the game.
I don't know how old you are, but my I remember when I was pregant with my oldest that my mother thought she was pregant as well -- the home test was positive and my dad was panicking -- he was nearing in on 60 at the time -- a bit older than my mother. She went to the doctor and it turned out she was starting the early stages of menopause. They were both quite releaved.
