Bleeding 2 days after Positive OPK

Momma2009?? • Expecting baby 5 early Aug 2015! ??
Has anyone had period like bleeding 2 days after a positive OPK? It's not red like a period it's pink. More then a panty liner but not enough for a pad. 
I called and set up an appointment with my midwife. I'm just wondering if anyone else has gone through this.
