Natural birth control

Looking for suggestions on natural birth control... I'm 3 weeks pp and thinking ahead to my 6 week appointment... I've tried all types of the pill before and I can't deal with how it effects my hormones... My husband and I just used the pull out method before we were ready to have our first but this time around we are looking for something a little more reliable as we won't be ready for a couple years to have another... I'm not opposed to using condoms however the latex hurts me so we have to buy special ones which are really expensive 😒
