Going on a week late

Im going on day 6 late of my period but I so have the mirena IUD for birth control.. my last 3 periods where light with spotting at times ive had unprotected sex but im 6 days late, my boobs were sore for about a week, I bloated and still feel a little bloated but not bad, had some cramps but never bled. So im just curious if anyone who has had the IUD if your period just finally over time just stopped? Or if thats even possible. Ive also struggled with my 8th yeast infection this year that I cant get undercontrol if that may play a part in why I havent started or not.
