12/24/15 Why are there brown chunks coming out of my vagina? They're like the chunks you get during your period since your uterus is shedding. But I haven't had my period since November 24-29. And according to my calendar my next period isn't set to start until January 6. So I'm skipping the entire month of December. The calendar I have to track my period has been 100% accurate since I downloaded it in early 2013. This is the first time this has ever happened. It's gross. Really gross.
