I need help PLEASE!!!

I believe I ovulated either June 30th or July 4th which would make me either 10dpo or 14dpo. Af isn't due til the 19th. 3 days ago mid afternoon when wiping I noticed pink discharge. lasted throught the day. following day got heavier but ONLY during wipes until evening where it was flowing medium. Today the flood gates have opened!! But my bbt is still high and has been. I'm like clockwork on my cycles. Any advice? Wal-Mart cheapie was bfn today with 2 hour hold.
