The answer is in your diet, your calories, and your workout.
Your diet is low carb and high in protein/fat. There is nothing wrong with this. However you are depleting the glycogen levels in your muscles. Imagine that you lost a ton of weight and have been working out. You go out for a night of drinking, pasta, and fried food. You wake up the next day and you are like "Damn I look good!" Well that is because you basically pumped up all of the good parts of your body with carbs (simple sugars) while the rest of you probably hasn't changed much in one night. You are pumped up in this situation. Bodybuilders starve themselves and then carb load on day before competition. Now you are doing the exact opposite to your body. I hardly see any carbs in your diet, so your muscles are a bit deflated compared to how they were. Therefore making the fat more noticeable.
You are lifting weights. Lifting weights while on a calorie deficit will also result in the lowering of glycogen levels. Your muscles are working hard but aren't getting the calories that they are expending.
So what do you do?
I was a personal trainer for years and your story is the most common. I don't know how many times I had to tell women to stay on course and many decided not to. With men even with the drop of glycogen levels in their muscles they often don't see the dramatic differences and once they do, their muscles are actively growing fast enough to offset some of these appearances.
Given that you are an average active woman, you do not have the muscle content a man does. So a month of low-carb and weights has deflated your muscles and in essence has put a spotlight on any fat that you have.
My suggestion, keep the course. And of course if you feel better that is a great indicator that you are doing something right.
If I were your trainer I would suggest a little bit more carbs, a little bit more fruits/vegs, and less nuts, avacados (maybe more lean pork/chicken too). I would want you counting calories but not losing weight but not gaining either. If you are gaining then you need to start counting calories or slowly cut back until you stabilize. And I didn't get from your question what you were doing with your cardio. Not sure what you did in the past but there is no reason that you should have quit all cardio now.
At 4-5 months of this continuous training you will get a much better picture. If your intensity is good and you aren't fudging with your food intake you could see some really dramatic results. Not only will a weight program really tone your body but it will raise your metabolism and make cardio easier. I know that 4-5 months seems FOREVER but I have never heard anyone complain about their results after going through this period. The worst case scenario is you have built a strong muscle foundation, your body is tone, but you are packing a little extra fat on top of muscle. Given this a normal "diet" and a little extra cardio will take you to whatever you want your body to look like. Getting that foundation is key though.
