The hormone levels don't stay consistent in your system unless you take them approximately the same time each day. It lowers the effectiveness
Decreases the effectiveness just a little bit. But, with the fluctuation of hormones it may make you feel 'hormonal'. You really should take them at the same time every day.
Tiny risk of ineffectiveness. You might want to ask the doctor about additional options.
Hormones have a half life, I dont think its a big deal you can take them any time during the day, as long as its on the day.<br />
Depo is a different beast though.
