Don't rely on charting. You may not ovulate at the same time every month, and the temp. taking is not fool-proof. It is not as effective. I know the charting method well, but that is because I'm trying to have a baby. There are some really low hormone pills you could ask about. I always used Nuva-ring, because pills made me feel horrible. If you chart as your protection, I'd suggest using an organic condom at least. Don't take a chance unless you are with someone you want to have a baby with in the future. This is just my opinion...
