How soon after an earlobe piercing can you start changing the jewelry?

The recommendations I’ve seen have varied wildly from 6 weeks to 6 months. The obvious answer is “once it’s healed enough”, but I am not sure how to judge that. I got my lobes pierced about a month ago, and I’m eager to upgrade from the simple silver studs! But I also don’t want to risk damaging the healing process and making the piercing angry.

Any advice is appreciated 😊
