question: i have three children of 9,7and 3. i fell pregnant within weeks of starting to try. i had the mirena after the second, and when it was taken out, concieved our third that day! so no problems there! i also had a mirena fitted after my third and now we decided that we would like to try for our fourth so had it taken out. we have now been trying to concieve for eight months and nothing has happened. As i had no periods with my mirena in, i didnt know what my cycle was so i have been doing opks every month so i know that i ovulate. im really scared the coil may have done some damage.
