I have had my Mirena in for almost 5 years. I had it put in 7 weeks or so after my son was born. It settled in the cervix within the first few days. The strings were too long and they were hanging outside of the vaginal area. It was extremely uncomfortable. I went back in to have them cut and the length was great ever since. Other than it was poking my husband during intercourse. That effect took about a year for the strings to soften up. The first 2 months or so I had bad bleeding almost what is was like after giving birth. I do sometimes feel it inside me, especially when I get cramps. Sometimes I go one to two months without a period then when it does come it's heavier than normal. But not bad enough where I can where a tampon. Within the last year and half I have become bloated most of the time. I go a week or so without bloating. I usually get cramps for two weeks before my period starts and it comes every 24-26 days. I'm cranky too. I cant' wait to get it out!!!
