Birth Control..

I really want to get the iud but I'm scared of the side affects.. I don't want it to make me bleed for weeks on end or change my sex drive..but I feel like that would be the best and most effective for me out of all birth control methods.. I've had too many scares since me and my bf use the withdrawal method which I don't even like calling it a method tbh. I know I need to do something.. but I'm scared the side affects won't be worth it. But I definetly do not want a kid rn. 😔
