Your Progressed Sun and Moon are conj your natal Merc in your 3rd house. So I can understand your "feeling" of change or opportunity. The Moon will soon be moving on (one degree a month) but the Sun will be conj your natal Sun for a year or so.
You don't mention which area in your life you feel you could use these new energies (work, love, travel, more education, etc,) It might help to do that.
Also if you could post your solar return chart for the current year 2017-18 it might provide clues to which transits will be most powerful. I'm voting for Jupiter into Scorpio. But I need more info - more context.
