Post Partum Birth Control?

Alright I just gave birth to my handsome son a month ago. So I’ve had a lot of ups and downs since the birth. Now me and the father are ready to start swinging again. Of course we don’t want another baby for the next 4 to 5 years. I haven’t gotten my first period yet so the pill is a no go. We’ve been using condoms, but my partner goes numb after a little bit. So he takes it off and uses the withdrawal method. So I’m thinking now until I get my period that we should use spermicide and condoms. Any suggestions? Also brands?

Ps: My Partner Has A Latex Allergy!😕
