"previously, i had an iud (mirena). after 3 years all the sudden that caused me to start having terrible headaches and a lump in my breast which went away. i waited 3 months to get my body back to normal before starting sprintec. it works well at prevention, no more headaches,  my boobs have been sore and have grown almost a full cup size in just 2 months. it has increased my appetite. i&#039;m very skinny always been about 100 lbs. i have gained 4 lbs in 2 months. this never happens. i do not fluctuate in weight. i haven&#039;t decided if i like it yet. i&#039;m happy with my weight, but i&#039;m a little worried if the increased appetite keeps up if it will taper off soon or continue.?"
