Have had my mirena since ds2 was born and just love it (so, nearly 3 years). All has been well - dream product and would recommend especially since I haven't had a period since ds2 was conceived (i.e. not ovulating with Mirena). However, I've been bleeding sporadically for the last three weeks (first time since insertion) and it's been heavier the last 2-3 days including 24 hours of bright red blood. Not a large volume. Do know that some people do have periods on Mirena but not sure if this is one or not and why, if so, it's been so long. I'm from UK but not there at the moment (in Australia; Medicare covers immediate necessary care only). Do I need to see a GP/go to ED or is it just one of those things that happens sometimes? Advice appreciated.
