Birth control

My partner and I are quite sexually active and always use a condom. I've always got this thought in the back of my mind, what if the condom breaks? I've been to the doctor to get the pill but I am so unorganised and hardly remember to take it. Would it be worth me getting the rod? I've heard it can make you very moody and hormonal. I'm already mentally unstable as it is and don't want something like that messing with me. Is it really as bad as people say it is? Should I bother investing or just try my best to take the pill? Thanks.
