Brown Discharge: Pregnancy?

Emilee

I’m on Day 27 of my cycle and my period is 3 days late. I’m on Sprintec and have never missed a day. Today I have had lots of nausea and smell/food aversions as well as a very dark brown, thick discharge. I’ve never had this kind of discharge before. I have not taken a pregnancy test yet, but has anyone experienced something similar?
