"after giving birth i was looking for a birth control that would let me breast feed without any problems, my ob suggested mirena which made me a bit nervous because of the mix reviews i read. finally i decided to get it, the insertion was not painful at all ( maybe because i had just giving birth) i did feel a little bit of cramping that day and the following, but nothing major. i&#039;ve had it for three months now and i have not had any side effects. my period is very light now, no weight gain, headache or mood swings and most important no acne, that i have had problems with in the past. i am very happy with mirena so far, i hope this helps."
