For you, the first Mercury retrograde phase of 2018 is going to work to your advantage, especially when it comes to home and family matters. Mercury will normally move through in just 15 days, just long enough to get your head in the game, ideas on the table and the communication lines open, before moving on. Turning retrograde means that Mercury is here for two months and they coincide with the two most important months of the year for home and family matters.
