I'm not an Astrologer. On a personal level Astrology has never worked for me. But I have studied Mercury Retrograde for many years and it does appear to be valid.

If you don't know all the rules of Merc. Retro you may want to find a thorough explanation.
There is a very good one on Susan Miller's Astrology Zone site.
I usually make my own Merc. Retro explanation each Merc. Retro. Phase. Each phase usually coincides with a Full Moon.
This Combo can make for some intense and explosive natural disasters. It appears to play hell on anything mechanical or electronic. And some other bizarre things can occur.
Special Note: This Mercury Retrograde applies to all signs of the Zodiac not just to the signs it retrogrades in.
April 2017, Mercury Retrogrades in Taurus
When Mercury goes retrograde in the earthy sign of Taurus, almost nothing gets done in life. You would have made multiple levels of plans but everything just goes haywire. You would be stressed and strained and emotionally drained to the core. Add to this financials might get hindered. Though you put in much effort nothings comes out of it. Communication in personal and professional life gets a beating. It is best advised to wait for Mercury to go direct.
