Honestly, it really depends on the type of reading more than the timing. If it was a general reading, a month might be too soon since you’re still in the same energy.
But if things have actually changed — choices, feelings, whatever — then another reading makes sense. Tarot has a way of repeating itself if you’re trying to confirm stuff you’re not ready to process. The message will just keep popping up until it clicks.
So don’t stress about annoying the reader — just see if anything’s actually shifted since last time. If not, the cards will basically go, "I already told you"
