THIS HAS NEVER HAPPENED BEFORE

Coco

So I got my period 34 days into my cycle which has never happened to me. My cycle is usually 27 days so when this happened I instantly thought that I might be pregnant. I ended up taking a pregnancy test and came back negative. I thought maybe I might’ve taken too early and try taking the test again next week. Come to find out I start bleeding this morning which I thought was spotting, but it was way too heavy to be spotting so I believe it is my period that finally came. I don’t know what’s going on. I am planning on going to see a doctor. Anyone have any ideas though?
