Late period..

My last cycle was 35 days. That was the longest it has ever been except for this month.. My last period was jan 31st. Glow said I was supposed to start on the 3rd. It's the 7th. I'm on cd 36 now n still no sign of it. My nipples were sore for a few days n stopped. N on 12 dpo I believe or so I had discharge with a mix of brown n then later that day I had discharge with a mix of pink n it stopped the same day. Any help?
