brown smelly discarge?

Signe • Denmark • Feminist
I'm inbetween ovulation and my period right now and the last two days I've had brownish and pinkish discharge, that smells awful and strongly, as well as if someone's poking at my lower abdomen.
I'm scared that something is really wrong! Because googling my symptoms have only scared me so much.
Facts: There's seven days before I start my period and I'm not sexually active. 
Could it have something to do with that I've just started fingering myself after a long pause?
