"i had mirena put in after having my 1st child. i had it removed about 2 years later to try for baby #2. i never had any negative side effects while using mirena. i had no periods, spotting or cramping. my husband couldn&#039;t feel the strings. no weight gain or any other horrible side effects. it was painless inserting and removing mirena. and i got pregnant with baby #2 1 month after removal. overall i loved this birth control. i have read alot of these reviews with negative comments and alot of these people say they don&#039;t have any children. mirena is supposed to be used by someone who has had a child. maybe that is the problem.
