YOu cannot be wishy washy about birth control, either you want to be on birth control, or you do not.
It cannot be both ways. AN IUD is just as effective as sterilization, and has no hormones, so there are not side effects like the pill.

You take BC, you do not have babies. If you take the pill everyday, not missing pills, or "Well I would not mind if I got pregnant so I'll miss 4 or 5 pills..".
You do not take BC, and you have babies.
