Hopefully you understand that this doesn't matter in the slightest to the point of what I stated.
If you hear someone saying "if you can’t afford to have a kid don’t have sex" with regard to abortion, specifically, then what, do you estimate, is likely the driving factor for that having to have been said at all? My first guess would be "religion" each and every time. That religion is pitting some "pro-life" person against a "pro-choice" person, and this is a defense point in favor of outlawing abortion. Doesn't even matter "what religion". Obviously we'd most likely be talking about good ol' Christianity given this topic... but the fact that it would be Christianity, top of mind, doesn't matter. Last I checked, Christianity is a religion.
