Yeast Infection. HELP

Hi ladies! I am a bit scared at the moment because I am experiencing a yeast infection but I discovered that I was spotting while having this infection and as the day went on I had bled a brown substance...

This has never happened to me before!

I’ve taken a plan b 6 days before I had gotten an infection and my period is no where near time for me to get on it.

I haven’t experienced any pregnancy symptoms either!

Also! I’m just itchy down there... no smell..

What’s going on?
