yeah, it started by entering my 12 house, but I do have Saturn conjuncting ascendant and the last year natal Pluto too in the first, and it is about to conjunct Uranus POF and Juno in the first too. I know that it has been so long because I am monitoring the conjunctions on astro.com to see when he will start separating from both natal Pluto and ascendant. It has started separating and it will completely leave my ascendant in August. It can happen that Saturn can conjunct by applying and separating your ascendant for more than a year because it moves extremely slowly, it becomes retrograde in an extremely slow motion, when it becomes direct again it stations in some degrees for almost a week, etc. Bottom line, if Saturn hits your ascendant, get ready for about 2 years of misery. Maybe misery is felt more because it was in virgo this time which is a hypochodriac, miserable, nagging sign by nature (no offense to virgos out there).
Transiting Pluto is the one that is conjuncting natal Jupiter in the forth house, not transiting Jupiter natal Pluto. As I said, transiting Saturn is conjucting as we speak (since October until some time in the fall I think) my natal Pluto and it has been the period that I have literally been drained financially, but I am paying old mistakes, because I WAS careless with my finances in the past!
But in general, as the previous people said, this is usually a VERY slow period, where your life gets into a long stalemate, nothing happens, and you become sick of yourself and your suroundings. My experience.
