Nothing can beat your charms and your assertiveness, not even square from Saturn to your Ascendant. It can be a truly productive period when you work even harder to assert your qualities. You will probably appear more reliable and more committed.
Saturn making square to you Moon can be a much more emotionally draining transit. In order to understand what changes this may bring (along with Saturn transiting forth house) I need to know the following: Natal placement of Saturn and the houses ruled by both Saturn and the Moon. So far I can only see that your relationships may be challenged by this transit and that your house situations will undergo some fundamental changes. If you decide to post your chart so that we can have a clearer picture, here are the instructions:
T Saturn going through 4th
“This marks a time of considerable inner "re-working”. In terms of outward signs of achievement, this transit may be the most unremarkable of all the Saturn transits. However, near the end of the transit, and certainly later than that, you will recognize this stage as a critical one in which you made some life-changing personal and psychological advances and developments. During this stage, you are working on solidifying your identity, exploring your roots (where you came from), so that when Saturn begins its transit through the fifth house, you will be ready to differentiate yourself from others and embark on some important work on your ego. For now, however, you will face issues surrounding your attachments to the past. Sometimes this manifests as literal re-organization of your home. Moving house is not associated with this transit as it would if, for example, Uranus was the transiting planet. If moves are made, you might encounter some resistance in yourself. This is not a time when you feel particularly brave in the outer world. However, reorganization in your home, and more importantly, in your soul, embodies the true nature of this transit. Many will go through a major “spring cleaning” inside. Limitations that came from early family conditioning will be brought to the fore. At first, there may be some frustration with your life to date, and how you have limited your opportunities because of early conditioning. A feeling of being alone and unsupported in life may dominate the early stages of this transit. Sometimes, delays and slowdowns are experienced in the areas of health, mobility, and career. As Saturn moves closer to the fifth house, a feeling of some kind of mastery will empower you.“ http://www.cafeastrology.com/saturntransitinghouses.html
All transits simply act as background influences until they make a mathematical aspect to another planet or angle ie: Ascendant and Midheaven.

“Transiting Saturn square or opposite your natal Mars. You may have a hard time getting your way now. It may seem as if others are conspiring to stop you. You may also be afraid to express your anger because it may bring on even more difficult circumstances. If you repress your anger and frustration it could build up until you explode. For this reason, injuries, especially blunt trauma and broken bones are more likely at this time. The best use of this time is to keep your actions secret (following Saturn’s agnoia principle) from others by conducting clandestine operations or by keeping as low a profile as possible.” http://www.astrology-x-files.com/transits/saturn-op-mars.html
The Saturn Moon transit can trigger a crises in your relationship which may actually throw you into depression (cancer rules your 12th house). Remember not to suppress your emotions, but to remain emotionally supportive of your environment. That’s the best cure for this tiresome transit. It all also depends on your natal Saturn and what house is ruled by Capricorn. If sixth as it looks here, this may also give you health problems. Take good care of yourself.This cookbook description of Moon square Saturn transit may be helpful to you:
“Circumstances may force you to look at feelings that you ordinarily might choose to avoid, especially if a realistic assessment of them is difficult or even painful. There is a possibility that you shut down in your interactions with those closest to you as a means to cope with a current situation. Even though the catalyst may exist in the present, the roots likely go much deeper. No matter what your emotional state, this period usually brings you in touch with your past in some way, particularly regarding your family, as it is within that matrix that many of your behaviors became conditioned. One lesson from this cycle is to learn how to distinguish between conditioned reactions and responses that are truly your own. Habitual patterns of connecting with others may become impediments to harmony as you may face the fact that whom or what you assumed as a supportive influence may no longer play that role. Often this is because the security you believed was there had no firm basis, which you likely see now. Having the reliability of your personal life called into question effectively can make you more self-sufficient and less dependent on others for their support. While those friends that are solid likely will remain so, you may find that you spend more time by yourself now. Sometimes it can seem you are alone even when you are with others. However, the purpose of this interval is not to cut you off from life but to reconnect you by recognizing the sentiments that truly are important and those that are not.
You may resist accepting the limitations that often surround you now. Family issues may arise that reopen old wounds or restate old patterns and can frustrate and obligate you in unwanted ways. Your home may require attention, which may divert your resources from other areas. Even in your daily life, you can encounter obstacles, which disrupt the smooth flow that you previously experienced. While any of these may seem like restrictions, they can serve to focus you on the significant matters of your life, matters that you may have neglected. By applying yourself to the task at hand and that task only you can do a better job than if you scatter yourself, and you can come to terms with the meaning of whatever seems an interference.
