What Are The Side Effects Of Cerazette?

Hi. Lately i have been feeling extremely fatigue, weak, achey and have been losing a lot more hair than usual. im wondering if it has something to do with the new pill that i have been taking? I started taking Cerazette. but i havnt been very good with it and keep missing pills which makes me then bleed. so im wondering am i just low on iron? should i stop taking this pill and find another contraceptive as i clearly am not very good at remembering to take it.
