You guys im so p.o. help?

Ok so I have been working out constantly Since June 5th and eating as best as I can. Gs, veggies, carrots, as healthy as you can think of. I started off weighing 156 and now with all that hardwork I weighed by self this morning. I only lost 3 POUNDS. I'm so pissed. Is there a way where I can lose 7 more pounds by the end of this month?
