Bc methods

I just gave birth to my baby boy and don't want to get in Bc because Bc hormones do my body & mind wrong asf and I want to be 100% for my family and specially my son. I dont want to be sick or emotionally depressed. I also don't want any more kids (Just wana have 1) what else can I do ? Also ! My husband is allergic to condoms and the pullout method worked till we decided to conceive our son (he was planned) but I'm scared of it because I know it's not secure.
