I've seemed to reach a dead end with my weight loss?

I've been doing my workout everyday, eating healthy and I have a goal weight so I'm upping my workout time and cutting off more and more of my calorie intake. I've already lost around 7kg/15 pounds doing what I'm doing now but I want to lose more so I upped my cardio and strength training. It's been weeks and I don't see any difference on my body or on the scale anymore. Any advice?
