Skyla
"I've had Skyla for 4 weeks now. Yes insertion is very uncomfortable but it is worth it. I only had cramps the first 3 days after insertion and yes those were uncomfortable too but they stopped. I spotted for about a week after insertion and I have not had any bleeding since. I also have noticed a serious improvement in lubrication (I was on nuvaring) so sex is more enjoyable. Overall, I would recommend! Also, my boyfriend cannot feel the string and I can't tell it's there."
