Okay so I need opinions on BC, I've had the Mirena and had horrible side effects so I won't be going on that again, I'm currently on Depo but it made me BLOW UP!! So I'm currently debating the arm implant or back to the pill, I'm horrible at remembering to take the pill faithfully at the same time everyday, even if I set an alarm.
