Dark yellow/brown discharge

Logan
Hey, so the past couple of days I've occasionally had an unusually large amount of discharge (think a level teaspoon) each time. It has been almost jelly-like in consistency (stretchy, wobbled on the toilet paper, shiny), and very dark yellow-ish brown (think dark urine). 
I'm not too worried about the brown side, as I've been having diarrhoea, so that might add to the colour. However, Google isn't turning up much of anything specific, so I was just wondering if anyone here has any ideas. I'm in the 'fertile' (green on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>) phase of my cycle, if that helps.
