Hella confusing

Can any of you share experiences similar to this: missed period (4 days) 
Cd: 31, normal cycle 28/27 days
Negative hpt's to date
This evening I started bleeding bright pink, but there was a lot, only for a few wipes, however my cycles normal and i am ttc. I am not near home, and am actually in between doctors anyway so I'm trying to find practical experiences/advice for now.
