Lately I've noticed that I've had a lot of mucous-y white discharge, but you know, a reasonable amount hanging out in my undies. However, I just went to the bathroom and when I stood up there was a little white blob floating around that had obvious fallen out of my vagina. It was thumbnail sized and gummy looking. I feel fine, no weird symptoms, I'm not having sex right now... and my next period is weeks away! What is this??
