I had my mirena inserted 4 weeks after having my youngest daughter and it wasn't such a big deal, I didn't have a period from after I had it inserted and I didn't think much of it. I started have side effects about a year after it was inserted my back started hurting I had lost all of my sex drive couldn't loose weight and was loosing my hair to the extent that I could not put it up or I would pull out a hand full of hair it was even falling out by the handful when I went to was it. Well about 3 months ago the strings to my Merina fell out and my Merina became dislodged and was sideways not to mention I ended up with cervical cancer as well. I had to have a leep procedure done for the cancer and then they had to do a DNC to remove the Merina after it was removed it feels like a weight has been lifted and everything is slowly returning to normal I would not recommend it to anyone yes in some cases it helps prevent pregnancy but then the effects it has on some is not worth it. I would have rather brought another baby into this world insets of having to pay thousands in medical bills for the problems it has caused for me and my family!
