Losing weight...

So, I didn't really gain weight or loss weight the first trimester. With my first I didn't gain till 20 weeks when I was up 2 pounds. This time I gained 2 pounds at 12 weeks which put me at 122. I just weighed myself last night and was 119. So weird...I'm 15+3 weeks. I'm sure I'll gain it back hopefully before my next app when I'm 16 weeks...but anyone lose weight in their second trimester???
