My mom keeps asking me what I'm going to do for birth control after I give birth. I have PCOS so it took me years to get pregnant. I really do not want to get pregnant right away (I know a woman can be very fertile following having a baby) but I also don't want to go on birth control because the amount of time it took me to get pregnant after getting off it last time :/ I guess I have a while longer to think about it
