You are not going to lose 20 lbs in 7 weeks at your current weight. It's not humanly possible, not without resorting to dangerous methods that are far from healthy. You do not *have* to lose 20 lbs; you want to, but this is not a reasonable nor a safe goal for you.
You are not on a plateau. A plateau is not a few weeks; a plateau is when you're doing everything right, and months pass.
While it's frustrating to not be at some ideal weight for your wedding day, you can only aim to lose about 1-2 lbs, tops. Since you're under 200 lbs now, 2 lbs per week is likely too aggressive. So going with 1 pound a week weight loss (A safe, healthy attempt at your current weight) you can lose a max of about 7 pounds.
Add that to the fact that it can take as much as 6-8 weeks for healthy lifestyle changes to show up on the scale, I think it's time for you to re-evaluate your goals.
We can help you troubleshoot your current program, and see if perhaps there's something holding you back, but you are simply not going to lose 20 lbs in 7 weeks. You're not fat enough!
If you'd like more help, we'll need to more details.
