I've been on birth control (Yasmin) for about one year with absolutely no problems. My period has always come like clock work, always on the same day of the week, a Tuesday. I've never missed a pill and I take it faithfully about the same time every evening. On Sunday, I started spotting exactly nine days before my period is supposed to start. The spotting started after intercourse so I assumed that might have had something to do with it. On Monday, I still spotted slightly, and on Tuesday the same, yet it started to get somewhat thicker, not like the sprinkles of light blood it appeared to be on Sunday but more of a thicker brownish discharge and I started cramping a little. I called my docter and was told to wait it out until Tuesday, when my period is due to see what happens, and if needed I should go in. I'm not experiencing any vaginal itch so I'm not sure, although possible, if it's an infection. I'm a little anxious and was wondering if anyone might have any advice or can tell me what these symptoms may be a sign of.
