Its impossible for us to give you precise advice - this could be OK, or it could be a sign of a growing injury.
if you grabbed a hold wrong, and now your wrist is behaving oddly (popping in a specific position), I'd take it as a sign that you have a very mild injury / overuse, and to take a couple nights / a week off and see if it gets better. Maybe you should also climb a little lower grades / less strenuous routes for a little while. Continuing to train on it may be OK, or it may make it worse, there's no real way for us to know out here on the internet.
Supplements and taping with athletic tape both sometimes get recommended, but I've never had them work for me. Sometimes there's no substitute for proper rest.
