I am a 20 yr old college junior w/ my share of stress and money problems. My cycles are NEVER normal. I went off BC in June 06. My bf and I had sex, w/ condoms + pull out, on October 16 06. We also always check the condom after just to make sure nothing went wrong. I started having this stringy, brown discharge on November 15. I had a period for one day on Thanksgiving Nov. 23. I still haven't had a period every since that one day and I have taken two tests, both neg. I do urinate more frequently, I'm bloated, I am moody, but I don't have any other symptoms.
