"If you have a low tolerance for pain: Request a Valium (for before), and strong pain meds for after the procedure. This was the most painful medical procedure I have encountered so far (and no kids yet!). My body went into shock and shortly after I fainted off the exam table into my boyfriends arms, like a true Scarlet O'Hara. Extremely embarrassed, I made like a sloth and headed home to rest. The next few days were light spotting and manageable cramping. Moving fwd; your period will be more painful/heavier/longer. Take it easy when getting intimate after healing and invest in a heating pad!
All said and done; No pills, no hormones, no feeling it during sex or physical activities. It's the most practical BC on the market. Worth it!"
