When to start taking prenatals if we are wanting to actively try in April 🤔

We are currently not using any birth control except for pull out, so it’s a if it happens it happens stance. We both work in a school system and there are more ideal times to have a child, which is why we *fingers crossed* will get lucky and successfully conceive in the spring or summer. Just curious if we start end of March to baby dance, should I start taking prenatals now? I’ve read very mixed reviews as to whether it’s smart to do it this far out or not. Would love to hear if any of you have talked to a doctor about this before? Thanks! ❤️
