The first day of my last period was August 26 and ended September 1st. My bigfeiend and I had unprotected sex on September 12 and I've been slightly cramping since then.. My app on my phone says I ovulates the 11th. I've been getting hot flashes for the last few days.. My app on my phone says I should have started my period sept 25. I have a brownish discharge when I wipe for the last 24 hours. Should I wait it out or take a test?
