Birth control after baby?

Are any of you ladies thinking about birth control after you give birth? This will be my second child, and I have been thinking about birth control, but I'm terrible about taking medicine and I did the depo shot before and had horrible side effects, so I'm not sure what my other options are. I've tried talking to my doctor and he just said "we will cross that bridge when we come to it" but I want time to research the different options and know the best option..
