I am 52 and was on the pill for 27 years straight. Periods were so light that I tried to go off the pill thinking menopause was in play. For the last year have had irregular periods and 3 of them have been like the faucet you described. Heavy bleeding and uncontrollable. I have been told that at 52 it is almost impossible to get pregnant but not out of the question. I am sure it is just the menopause doing its thing, I wouldnt worry about it. Wish you well.
Sounds like you are reaching menopause. My periods became irregular, sometimes skipping 3-4 cycles. My last one was July, 2009. But, you could also become pregnant if you are still getting periods. It is recommended that you do not have unprotected sex until you have not had a period in a year or more. Good luck to you. Hope it all works out.
