"i&#039;m a 21 year old who has never given birth and had skyla inserted yesterday. honestly if i had it my way i would&#039;ve stuck to the pill! but as i&#039;ve recently been  put on medication that severely decreases the effects of hormonal birth control, iud it is! 
i took the 800mg of advil (and a klonopin) an hour before. this definitely was not a fun experience for me. and i don&#039;t say this to scare anyone, the pain is definitely uncomfortable, but my body went into shock after all the anxiety and i wound up almost passing out and throwing up. my doctor handled it great though, did an ultrasound to make sure my discomfort wasn&#039;t due to anything messed up. some people have strong reactions some don&#039;t. just know your body, 24 hrs later and i&#039;m all good!"
