Skyla
"For YEARS, I've been scared about getting an IUD.  I have sensitivities to metals and plastics. I've been talking birth control pills for close to 15 years. I'm 32 with no children and started getting migraines with aura because of birth control pills. I reluctantly made the decision to get skyla. The measuring and insertion is the most excruciating pain I've ever felt however it was maybe 30 seconds for each. Afterwards I had some pressure and an uncomfortable feeling inside my vagina. Also, felt like I needed to poop something out for an hour but....that was it. Totally worth it so far."
