Can Vibration Of Mirena Coil Cause Vaginal Bleeding?

Hi, I've just started using the power plus pro 1000 (vibro plate) in a quest to lose weight, no problems however after 1 week I have started bleeding. I also have Ednometreosis and have the marina coil which has been in situ for 10 months plus. I'm wondering if the bleeding may be caused by vibration of the machine? I don't feel unwell in any other way and would appreciate some assistance on whether I should continue to use these machines or not.....40 year old female, BM - Ayrshire Scotland
