There's nothing wrong with thinking better of it. It's a Pisces prerogative. Besides, it's probably a good idea given that Mercury, planet of the mind, will be turning retrograde in your zodiac sign on February 26th. This is when certain apprehensions resurface, causing you to stop dead in your tracks. Not only will you be haunted by feelings of something being off, but you'll receive strong prompts to reverse course or do an about-face. And you would be wise to follow them. It may not make sense in the moment, but trust that all will be revealed after the lunar eclipse in Virgo on March 3rd.
