Compression leggings for postpartum?

So I’m starting to prep for after baby’s birth cause lord knows I won’t have the time or energy to shop for myself once baby comes. Looking at getting some postpartum leggings and wondering if my regular fabletics or lululemon compression leggings would be basically the same? Anyone know the difference (if there is one...). And also when can I wear postpartum leggings? Right away leaving the hospital or once I’ve started healing?

I’m a second-time mom but my first is 8 and I can’t believe the stuff available now compared to before lol we had nursing bras and tops and that’s pretty much it 🤷🏻‍♀️ TIA!!
