If you are not sure if you are ready for another baby, and you dont like the pill or depo, I would either wait it out with the iud, or maybe try the patch, or just use male condoms. Just until you know forsure what you want. Condoms, if used properly are 99% effective birth control. Give yourself more time to think about the baby, and soon you will come to the right decision for you. In the meantime, protect yourself, even if it isnt with the iud.
