I had mine changed last month. Just had my first period after insertion and it was heavier and cramps lasted longer.

My last period, although it was short, was horrendous in terms of cramps. So I was bound and determined to not let that happen again, so started with ibuprophen a day before expected date, and took red raspberry leaf supplements to tone the uterus, and yarrow tincture when I started my period to hopefully lessen the cramps and bleeding. It did last 2 days longer than what it was before and slightly heavier, I'm going to try shepherd's purse next month.

But in all honesty, I can't wait to get this taken out. I always feel weird knowing there's this metal thing in my body.
