what should I do

So my and my partner have been together for almost 2 years now (he's my first) at the start of the relationship I wasn't on the pill and we were using condoms. About 6 months later I started the pill and stopped using condoms but he always pulls out and a year and a half later we haven't had any scares. Lately I've been thinking of using condoms again and be on the pill at the same time but I don't know what to do
