I am 37 years old and I had a tubaligation eleven years ago. I have been having sex all this time without any other protection as I have been with the same partner all this time. Well for about the last two weeks now I have been having cramps like period ones. There is a little bit of pinkish discharge off and on too. Is it possible and what are the chances of me getting pregnant? I have been kind of moody and it's tender with intercourse. My period isn't due to start for another week or so but the cramps have been awful.
