Are you planning on breastfeeding? If you are, that limits your choices drastically.

If you're breastfeeding it will either have to be a coil (mirena or copper), the mini pill or condoms/caps.
I had a mirena fitted after having my baby because I was breastfeeding and do not want to have any other children for a few years (couldn't be dealing with an unplanned pregnancy and the pop isn't as effective).
