I dont know if im losing weight fast enough or whats going on?

Today is the last day of my second week of me dieting and excercising and since I started I've lost ten lbs but I'm not sure if five of those pounds was water weight. I've noticed this whole week my weight shifted from 190 to 188 the whole week how come its not going lower? I don't know if its because my diet or if its because my excercise. I just want results. My diet is egg whites on whole grain bread with a glass of chocolate milk with no fructose corn syrup. Some nuts or non buttered popcorn and then for dinner its chicken breast with brown rice or mixed veggies. Some times its like two meals unless I ewake up early then its three meals. And I'm running for thirty mins everyday. I'm pretty sure I can lose weight from running because I've seen a really big walk to work everyday and he ended up losing a lot of weight. So I'm not sure why my weight is going from 188 back to 190 every day. I don't feel like I will lose much weight after this month is over and I have a lot of body fat in my chest and sides thatwill probally never gov away ): I'm male by the way.
