Waist shrinking but hips growing.

So I’ve been eating healthier and working out for a couple months now. I measure once a month right? Turns out my waist is shrinking, I lost almost 2 inches but my chest is the same and my hips have grown 2 inches. What the hell is this??? Lol now I measure 33 29 37. I figured I would be losing inches everywhere but it’s probably my work out routine. I haven’t been consistent so who knows??
