spotting vs periods

Annie

okay so I just had a quick question for those of you who have iuds. i have had my Mirana for 4 years and Im still trying to figure out my periods. sometimes my period is medium flow but then other times I just notice a tiny bit of bloody/clear mucus that's what the picture is.. my question is when that bloody clear mucus happens is that still considered my period or not I log everything and it just doesn't make since sometimes it will happen a week before my period starts meaning the actual flow and then my period will go away and the next week I'll have this light mucus again just curious if this happens to anyone else or what it could mean TIA
