Is this wrong?

My husband doesn't want anymore children right now but does in the future. Normally we wear condoms, but lately he hasn't been wanting to wear them and he has been pulling out. We used this method for years (but also was on the pill) a while back so he's "pretty good" at it haha. He now knows I'm not on any birth control but still continues to use only that method. I want a baby desperately so I'm hoping I get pregnant lol. Is this wrong? Have any women got pregnant this way?
