"i was on several different bcs from ages 15-20 and other than bloating and weight gain, i don&#039;t recall ever having a bad experience. i eventually stopped taking it altogether, however. as of recently (age 26) i began taking lo loestrin fe. i have never experienced something so horrible from bc in my life. i have bled so badly ever since i started it and have experienced the worst and most continual cramps. i have tried to push through it in hopes the pain would at least stop but it has just gotten worse. i haven&#039;t experienced mood swings or weight gain (as of yet) but would take either of those over the type of pain i am experiencing. for the record i am 5&#039;2, petite build, and 115lbs (should body size have any merit on experience)"
