This is an excellent time to bring the different facets of a plan or project together. Emotions run high during this period. The period from the full moon to the next new moon is a time to tie up loose ends and resolve old issues. Communications will tend to go awry during the Mercury retrograde. Phone calls, letters, e-mails and verbal communications may be delayed, misinterpreted or blocked altogether.
Car trouble is also common.
Merury's retrograde motion is more apt to affect you adversely if Mercury is transiting a planet in your natal chart during the retrograde.
