birth control
"As far as the effectiveness against pregnancy goes, skyla works amazing. My boyfriend of 6 years and I do not use protection and I have yet to get pregnant. That is about the only positive thing I have to say about skyla. Everything else is terrible. The risk of it embedding into or perforating my uterus is also a monumental fear of mine. Although I don't want kids now, I hope to have them in the future and my frequent cramps scare me even more that I may not be able to have children."
