TMI Photo Warning! Jelly like brown discharge?

We are currently ttc. I have long cycles of about a 42-45 day cycle and on cycle day 25 I started spotting brown. I'm going on spotting for 11 days now (day 8 had some red mixed in like a period, but not?) Today was different and I had a ton of light brown jelly like discharge with streaks of red in it. It also has creamy cm mixed in. What is going on!? I've gone to the doctor and he chalked it up to being mid cycle spotting.
 If this was a weird freak period I'm baffled. But my app says I can test in a few days because that's when my actual period is supposed to start. Sorry, for the tmi. I also don't think this is an infection as I have no other symptoms.  Has anyone experienced this and know what it could be???
