Question About Butt/Thighs - Please Help

Hi Everyone, I was wondering if someone could help me I have a question.

I suffer form PCOS and it's hard to lose weight, been battling the last few months, I use to jog around the park and with a proper diet lost about 20lbs in 4 months/

It's been up and down and I have another 50 to go so decided to get a machine to help burn fat and I added in some squats and push-ups etc...

So it's been 2 weeks in, I burn about 800 calories a day on the elliptical 6 days a week.
I've noticed that my work clothes are now more snug around the butt and thigh area. Why is this?!?!

I've not gained any weight and my butt and thighs are much much much firmer than before.
The measurements are the same so I'm confused...

I want to lose inches especially in these areas and I thought more cardio would help that, so why are these areas seeming to 'grow'?


Any thoughts?
Thanks a bunch!
