Run for cover! (Really, just kidding.) Mercury turns retrograde today, June 26 in Cancer; it will station direct on July 20. Since Mercury is so slow-moving, the effects of this retrograde period likely started being felt a few days ago, and the effects could potentially be felt for a few weeks afterward (until the end of July).
I‚Äôve 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 ‚Äúre:‚ÄĚ renewal, reflection, re-doing, recovery, etc. This is a time to use the powerful planetary energy to the fullest. Mercury retrograde in Cancer (a water sign) favors deep thinking and meditation. This is a time during which you may find yourself questioning your own self-imposed emotional barriers, or examining ways in which you could be more in tune with your family and your emotional ties to them.
Neptune is also retrograde during this period (through November 13), as is Pluto (retrograde through September 20), so you will have the added attention to feelings of renewal and new beginnings (Pluto) and intuition (Neptune) during this period of Mercury retrograde.
