Okay so I know that vaginal discharge can be many consistancies and colors... mine is usually a really light yellow and pretty runny. Okay this is gross but tonight I had a decent-sized chunk of mucus... I'm not due to get my period for another week and a half. I did just skip my birth control this month and I know for a fact I'm not pregnant. Is this just a random woman thing or should I be concerned? I'm 19.
