Period help!!!!

So I was due for my period last week, I had some VERY light spotting for one day, a lot of bloating, but no real bleeding. I've had my Mirena for about 7 months now and although my periods were never regular, I've never spotted for a day then nothing. I had slight cramping also. About a month ago my boyfriend accidentally came inside me, but I don't think I'm pregnant, any ideas what it could be?

Also, I got a yeast infection when my "period" was supposed to end. And now it's cleared after using an overnight suppository. Has anyone had anything like this?? I'm stressing
