I got my Mirena coil fitted in March and the first 10 days were great! But after that it all started going down hill... I was spotting everyday and I had to go for a scan because they couldn't find my strings but it's still in place. I'm now 5 months down the line and I seem to have a light period (like spotting) one month then a heavy one the next?! When I have a light period I still get the cramps but no real bleeding? While the spotting has stopped its the heavy bleeding every other month that's getting to me, has anyone else experienced this? I can't shift any weight, I have no sex drive and my mood swings are awful! Is this all to do with the coil? I thought it would have settled down by now :(
