Hi, My periods are irregular, I went the whole month of December and the whole month of January without a period. In February I got my period the 8th and I was intimate the 18th without protection. He did pull out, but I know that s not always effective. I also took one of the Plan B pills, but I recently found out that only taking one was ineffective. Around the 28th of February I got a brown discharge and afterwards I started spotting day after day. It changes color everyday. One day it can be brown, another pink, and sometimes red. I am still spotting and this is day 14. I m not quite sure what s going on. I also took two pregnancy test a few days after my spotting was starting to occur, and both came out negative.
