Brown discharge?!

Ok so I have HSV2 and am having a herpes outbreak atm, it's taking a little while to heal. My period is due round about now but I came off the pill 2 months ago so I'm not massively worried about it and I have been having some minor cramping feelings the past couple of days. Anyway, I was using a mirror to get a better view of my floo while I was putting some tea tree oil on the sores and noticed a brown watery discharge wtf?! I noticed it when I wiped was assuming it to be old period blood but it (forgive me for sounding stupid) wasn't near my entrance, it was in between my flaps? what is going on?
