Postpartum face change?

J

I am 5 weeks PP and around 3 weeks I started feeling like my face looked different. I only gained 26 lbs during pregnancy and have 7 left to lose. I am a petite person so i currently weigh 125. I think what is bothering me is I noticed a little bit of skin under my chin almost like a small but noticeable (at least to me) turkey neck. Did anyone else go through this? Maybe my face was bloated during pregnancy and the skin stretched? I hope it shrinks back bc I’m feeling really upset and insecure about this
