How long after delivery do you stop being swollen and horrible down there/ in general??.. 😩😳

My ankles and feet were swollen by the end of the night 😩 but I enjoyed my cousin’s wedding 💜
Anyone start to swell in the face and feet/legs at the end of your pregnancy between 37-40 weeks??? I feel like my face is swollen 😩🙄😭
If so why does it happen?
What's everyone's worst part of being pregnant? Mines is not being able to walk comfortably and extremely swollen legs and feet 😩😩
