I don't think any one of us can possibly say whether this is enough cardio for you to lose weight. This cannot be stressed enough, but every single one if us is different and our cardio versus weights needs are different. What works for me, 3 cardios per week, but I often only manage 2, may be useless for you. You really have to just use trial and error and find out what combination suits you best.
Regardless of weight loss, which, personally, is a particularly unmotivating one, three cardios per week is a good minimum to adhere to for heart health. If you can set goals based on a desire to be healthy, run a 5k, or something similar, you might experience greater success. As you aim for greater fitness and health, let the weight take care of itself. Just a thought.
