last few pounds

hi everyone,
over the course of about 6 months i have really changed my life style and eating habits. i eat so much healthier and i work out about 5-6 days a week. in total I've lost about 8-9 pounds. i currently weight 120 and i am 5'6. i am a little frustrated tho because i can't seem to lose another pound. the past 2 months no matter how hard i try i can't lose any more weight. it'll go to 119 then jump to 121 after i work out and eat healthy. my work pants seem to be getting a little looser and looser but the scale does not go down. am i still loosing fat even though the scale doesn't budge. i have been doing a little more weight training lately and my body seems slimmer/leaner but i just can't lose the last few pounds that i was hoping for. sorry if it doesn't really make sense! lol
