"i have been using loestrin 24 for at least 3 years now, with no problems whatsoever.  i&#039;ve never had breakthrough bleeding.  i did not experience weight gain or any abnormal side effects. and my periods have been light, and very predictable.  i&#039;m going to try seasonique starting in a few days. (i just like the idea of only having 4 periods a year). i have a feeling though, that i&#039;ll end up switching back to loestrin, because it was been very reliable for me."
