The problem is twofold here. WEight loss is about the food you eat... not the exercise you do. You may not feel comfortable keeping a food journal, but tracking your nutrition is the single most powerful tool you have available to you. People as a general rule SUCK at estimating how much they're eating, and almost always underestimate. That's how we gain weight in the first place.
You may not have a year to lose the weight, but your body doesn't care about your schedule. What is realistic is that the less you have to lose, the longer it will take to lose it. If you're over 300 lbs, losing 100 lbs in a year is easy (relatively.) When you're down to the last 10, you're looking at a 1/2 a pound a week or *less* on average. Losing weight on a schedule is a great way to land yourself in frustration and failure. That's because our bodies abide by certain metabolic processes that don't care about special events.
A good rule of thumb is about 3% of your remaining weight loss goal. IF you have 20 lbs to lose, that means you can reasonably aim for .5-.6.
At 10 lbs, that's more like .25-.33 lbs weekly.
Aiming to wear a certain pair of jeans is usually unreasonable. You buy clothes to fit your body; you don't force your body to fit certain clothes.
And always, there will be weeks you lose, weeks you don't, and weeks you may even gain. If you're female, this can even because caused by fluctuations in hormones.
At 5'2 and 140, you're only slightly overweight. If you lost 20 lbs, that would put you at the low end of a healthy weight. Whether or not you can even achieve that is a whole 'nuther story. When I was in college, I was 5'7 and 145, and I looked downright skeletal. I have no desire to achieve that weight now, and I couldn't maintain it if I tried. My goal is a more reasonable 155, because I lift weights, and will have a higher muscle-to-fat ratio.
If you want to lose weight, you're going to need to track your nutrition. If you don't, you may never have the information you need to actually lose weight. If you're exercising, and not losing weight, then it's your food. You can't out-exercise a poor diet.
