Something like an implant or IUD would be a really good option for you because they can last up to 5 years and you wouldn't have to remember to take it like a pill. I think it's good that you recognize that you're not in a position to have children (at least at this point in your life). I strongly believe that people shouldn't have children if/when they aren't prepared-- not everyone is cut out to be a parent. It's a tough job!!
