3 week periods?!?!

Beth

I’ve had the implant now for roughly 2 years and I pretty much have 3 week periods about every 3 weeks sometimes 2... is this normal? Has anyone else experienced this? They’re so light for the normal 3/4 days and then they stop and I think Yay.. but then they seem to come back again and go on for the rest of the 2/3 weeks before they stop again, it’s so weird! Need to know it’s not just me 😫😫😫
