<s>[INST] Hi I had the mirena coil fitted May 2010 (due to heavy constant bleeding ), I was told it would last approximately 4 years. I have had it in now for approx 2 years and 9 months and over the last few months I have felt really low, lacking energy and constant symptoms of starting a period. Today i started bleeding. I know there are no guarantees the coil would last the full four years but I did not think it would wear off so soon. Is this something I should go to see my GP about or is it normal. All help really appreicated with this [/INST] Hi, Thanks for the query. Sometimes breakthrough bleeding, inter-menstrual spotting etc. can be seen while being on the intrauterine contraceptive device. So possibly your symptoms will subside soon. But if the symptoms persist better to consult gynecologist once and check if the device is in place or not and also verify about its efficacy. If everything is normal you can continue with the device for approximately one more year. Take care. </s>
