Hips widening

Has anyone else noticed their hips are much wider after giving birth? I’m only up 3lbs from my pre-pregnancy weight and I’m 2 pant sizes up. I feel like I look the same but when I went to try on clothes I was surprised nothing came close to fitting that was my regular size. Has anyone else experienced this and do they go back to how they used to be? I’m 5 weeks pp today. Hoping I don’t need to buy all new pants 😕
