When Mercury swims through Pisces, logic is diffused. But what happens when Mercury swims backwards through Pisces?
Mercury will go retrograde at 19 degrees Pisces, on February 23rd. All the usual rules will apply; double check the details, expect opinions to be changed, avoid signing major documents (if you can). But in dreamy Pisces...
I will say this: don't worry about it. Really. You're already in the deep waters of this Pisces stellium, so some second thoughts aren't going to make a huge difference. And that's all Mercury retrograde is; a time to reconsider. Pisces energy has compelled you to let go. You're allowing things to happen and going with the flow. You're feeling almost Zen about the whole thing because you've realized that certain things will happen, with or without your intervention. But maybe you missed something (Pisces is notorious for obscuring the the truth). Mercury retrograde can be very revealing when secrets come to light.
For those who want to go deeper, this is the ideal energy for creative exploration, meditation, and getting in touch with some old hopes and dreams. Are they worth a second look? Obviously, this is a poor time for starting something new. No one's really sure what they think, and ideas will shift like crazy. Mercury will back into Mars on February 26th (at 19 degrees Pisces), which suggests that your last big idea/plan/disagreement will be up for review, immediately. So be prepared to reenergize something you thought was finished.
Allow information to bubble to the surface, but try not to act on it until Mercury goes direct (on March 17th, at 5 degrees Pisces). Those with planets/angles between 5 and 19 degrees Pisces, Virgo, Sagittarius and Gemini will be most strongly impacted.
