"i&#039;m 18. i&#039;ve been on this pill for 5 months and i am switching as soon as possible. this pill causes me to have intense cramps. not just while i&#039;m on my period, but all month long. they are so painful i have to lay down in a fetal position until they stop, which is usually 15-30 minutes. besides the extreme pain, i also experienced bad mood swings. the week before and the week i&#039;m on my period i am a raging animal. it is very hard to control. i&#039;ve used several other birth control pills in the past two years but i have never experienced pms like this before."
