I know this might sound a little dumb

, but please bare with me.
My wife is taking Seasonique, and we're wondering if we can have sex without a condom? Both of us are STD free, and she's been on it for a little over 1 1/2 months. We're not ready for a baby yet, but are wondering if there would be a risk associated with it, or if we should just stick with using condoms also.
Thank you in advance for your help.
