What in the world is this?

So I just checked my underwear because I have been spotting for the past few days but I saw this in there and I want to know what the heck is this? I went to the doctor today, the chances that I'm pregnant are VERY low, and I have been having numerous hormonal imbalances today. Can anybody give me some insight? Sorry for the photo. Thank you

Oops, never mind about this discussion! I wasn't aware that you can't post photos on this site

You can post photos though.  This should help:
