Levonorgestrel
"Took a 800mg ibuprofen an hour before insertion on 2nd day of period (I always spot on first day) insertion didn't hurt it felt like a pap smear. I was nervous for no reason. I usually get really bad heavy periods but the day after insertion my period went straight to spotting and minor cramping. It's going on 2 weeks and I'm still spotting. My gyno told me it's a normal side effect and give it time to adjust to my body. I get cramps everyday but nothing I can't handle."
