Is it safe if....

So I was previously on a balanced estrogen/progesterone birth control, but I got off it for two weeks then switched to one that's more progesterone then estrogen. I've been on it a week, and Id like to know if I can have sex with my partner without a condom (and using the pull out method) im allergic to latex so it's kind of problematic. I don't want to get pregnant, and im not sure how effective the pill is right now
