What's going on??

Bristee
I'll try to keep this short and to the point. I need some insight as to what my body is doing!
3 months ago I had my last period after taking my last bc pill. Since then, there has been no sight of an incoming af, or positive pregnancy test. I have no idea where I'm at in my cycle. 
Yesterday, I started having verryyyyy light, pink spotting. I assumed af might be getting ready to start. 
So about 2 hours ago I put in my diva cup, only to discover heavy egg-white, BROWN cm in it an hour later.
 What is going on??!! Is it just my hormones still trying to get back to normal?? I've NEVER experienced brown discharge and it's kinda got me wierded out...any insight/opinions ladies?? Thanks!!
