Late period..

I am 6 days late today. My normal cycles r 31-32 days. My last one was 35 days. Which was unusual. I'm on cd 38. I had sore nipples for a few days. N on 12-14 dpo, one of those days. I had discharge with a tint of brown and that same day it changed to a tint of pink. N it stopped that day. The sides of my boobs r sore. N they feel alil fuller.  I need advice!! Please and thankyou!
