The last time I was sexually active was last Tuesday night, and this past weekend I had some light spotting on my underwear. One morning when I went to the bathroom, I flushed the toilet and noticed what appeared to be a thick brownish (or reddish, I don't remember, it was really late in the morning and I wasn't wearing my glasses) discharge floating around in the toilet.
Unless I have the world's worst memory, I haven't had my period this month. What could be wrong/causing this?
Thanks in advance!
