Existant symptoms and conditions

ok, so i started taking Loestrin in June of 2007 and it was great. i had really bad cramps and had been having problems with my periods for years. then my doc put me on Loestrin and all my problems went away, no cramps no problems at all. then 6 months after being on the pill and for the third month now my cycle is pretty much none existent, theres just this dark brown discharge-like substance! more like clots. is anyone else having this and is it normal?
kinda worried!!!

Beginning the day after I take a Viagra. I have a very weak almost none existant urine stream. I have to take a Flomax to get back to normal.
Any one else have this problem?
