Hiya i'm new to this but have read many comments about mirena coil. I had mine fitted in November 2010 and so far have had no problems plus no periods which is brilliant. This week I have been feeling queasy, tired, weird feelings in my tummy, jeans are a bit tight, very emotional plus my breasts have got bigger and are really sore - my hubby noticed that straight away as he did when I was first pregnant with my daughter. I have done a pregnancy test which was negative. I think that I should go to family planning to find out what is going on in my body and I am early 40's. It feels like when I was pregnant but really don't know.
