Run for cover! (Really, just kidding.) Mercury will turn retrograde tomorrow, February 23 in Pisces; it will station direct on March 17. Since Mercury is so slow-moving, the effects of this retrograde period could potentially be felt for a few weeks afterward (until the end of March).
I’ve stated many times before that Mercury retrograde is truly not to be feared. While periods of Mercury retrograde are not ideal times to begin new ventures (and you should be extra careful with details of communication, travel, and finances), they are still powerful times of “re:” renewal, reflection, re-doing, recovery, etc. This is a time to use the powerful planetary energy to the fullest.
