Ethinyl estradiol / levonorgestrel
"This is the worst birth control pill I have ever used. I have taken it regularly daily and have bled for nearly three weeks with awful cramping. Plus the nausea was so overwhelming. My appetite has been nonexistent. My period came very regularly before going on Seasonique, every 28 days. But to bleed before the yellow pills and for nearly a month? I was checked out by my obgyn and there is no cause for this but this pill is not a good fit for me."
