Also, if you are BF'ing you can't be in hormonal BC. So Plan B wouldn't even be an option unless you can pump enough supply to last you for awhile. And it might also DRY up your milk. (granted this is only if you are Bf'ing)
And don't rely on the pull out method. It IS possible to get pregnant. You are playing with fire. There are many very reliable non hormonal birth controls. And you don't have to rely on just condoms.
I was using this spermicide jelly before TTC. It forms a temporary barrier around your cervix to block sperm, plus it has a spermicide to kill sperm. You just pop it in right before having sex (it takes just as long to put on a condom).
This is the one I used to use....https://about.pricegrabber.com/sear.../search=contraceptive+gel/st=product/sv=title
