"i had the mirena iud inserted about a month and a half ago. i cramped the day of a little bit and everything was fine. so far i love it, i have only had one period since and have been expecting a second and it hasn&#039;t come yet. unfortunately i am having it removed in a couple of weeks. my husband and i after having sex noticed blood in our areas- and it was from the strings of the mirena cutting him. this was really painful for him and it is not his first injury during sex since i had it inserted. i would recommend if your partner is rather larger than average that this may not be for you because it has been an issue for us since inserted."
