Had Mirena Coil Fitted, Heavy Period And Fibroids. Coil Out After Wiping. Am I Contraceptively Covered?

Hi, I had the mirena coil fitted in february due to extreamly heavy and painful periods due to fibroids . I still continuted to bleed heavy every single day since having it fitted. I went back for the 6 week check up and the doctor told me to persivere with it. I went back about 6 weeks later again, still with constant bleeding everyday and she suggested I take 3 packs of microgynon back to back so that my body can get used to the coil. The first two packs, I had less bleeding but was still bleeding every single day. By the 3rd pack, I was back to bleeding heavy every day again, to the point where I was bleeding through the biggest tampons (sometimes 2 in at a time), I come through my underware and clothes, I m 28 years of age and I have to have a mattress protector on my bed, it s getting very embarrassing and it s controlled my life for over 3 years now. Yesterday morning, I went to the toilet and when I wiped I felt a scratch , I wiped again and the coil had come out and I caught it on the tissue . I went to work yesterday and had to be picked up and taken home because what happend I can only describe as a gushing incident , it s so embarrassing especially as some of my co workers are male. I felt absolutley distraught. When the doctor told me to take 3 packs of microgynon back to back, after the 3rd pack I carried on taking a 4th and 5th pack in hope that this would stop the bleeding - It didn t though. I have an appointment on Tuesday (24th Jul) to discuss what my next option is as I don t feel that the merina has worked for me but I just want to know, am I covered contraceptivelly as I have carried on taking microgynon? Not that any sex has been able to go on, I m just wondering for peace of mind. Hope you can help? Thanks Kate
