Brown discharge.

Hey I'm very new to glow but wanted to seek some advice, I had a miscarriage at the start of sept and I finally had stopped bleeding and went into a normal period which finished last Tuesday, I also took an ovulation test to see when I would ovulate and I was ovulating that week.  I have had no bleeding or brown discharge until today, it was very light bit a bit concerned on why this has happened. Anyone any suggestions?
