Second stall?

Ok, I expected the week 2 stall because everyone warned about it. I am now about 2 weeks shy of my 3 month surgiversay and seem to have been stalled for the past week or so. I am trying to up my calories without carbing up but it's tough. I walk and jog most mornings so my excercise is good and, believe me I'm grateful for having lost 50 lbs!
I am only getting around 500-700 calories a day so I'm wondering if that is the issue here. Has anyone else had a stall around this time?
Thanks,

Tiff.....oh, and I need a new user name because I'm now Platinum blonde!

Yup... one of MANY stalls.... totally normal I think!
