How are things not going according to plan?
I note that Saturn square your MC is also Saturn square your natal Mars. The orb is wide with Mars, but because Mars is conjunct your IC--even with the wide orb--a square to either of them brings both into the equation. Meanwhile, transiting Mars retrogrades over your natal moon. The current Mars retrograde takes place in Saturn's domicile signs.
Saturn and Mars talking to each other like that could bring some frustration with trying to move forward. Mars wants to just do it. Saturn says wait, slow down, double and triple check everything, make sure you're getting it right the first time. And then, Mars going retrograde highlights whatever problems you might have as a result of putting out too much energy. If you're overworked and overwhelmed, it all comes to a head with Mars retrograde. If you're trying to push ahead with a flawed plan, the flaws in the plan show up.
Uranus is also helping Saturn out, as it trines your natal Saturn and, by orb, your natal Uranus as well. Since you have a natal Uranus/Saturn conjunction, both planets work in tandem in your life in general. Uranus makes you roll with the unexpected, and Saturn makes you use self discipline. Together, they insist that you be responsive to both those things at once.
Do you practice any kind of martial art? This sense of needing to simultaneously discipline yourself and roll with the unexpected seems very like martial arts to me. If you don't, taking one up could be a way to use the energies of Uranus, Saturn, and Mars that are highlighted in your life right now. Even if it's just something you do on the side, you would probably find the rest of your life working better, too.
