A little confused please help

Hi everyone. This cycle has been interesting to me. I started mildly cramping October 8th. I was supposed to have a period yesterday and two day before that I spotted a little bit. I washed and and that was that. It was gone. Very creamy the last week and a half. Its been showing a little tan color with it. It showed a little more pinkish discharge yesterday morning. The day before my period my nipples got tender now today i feel like I’m about to get a yeast infection. What is going on? Does anyone else go through weird stuff like this?
