Period Underwear for PP bleeding

Has anyone ever used the period underwear? I use a menstrual cup for periods but I was thinking of buying some period underwear for after birth. With my past pregnancies, I only bleed heavy for about 5-7 days afterward and then it’s basically light bleeding to spotting for the next second - third week pp. I’ve stopped bleeding around 2-3 weeks pp with my other pregnancies and I just don’t find pads comfortable when I’m not bleeding much so I was thinking of trying period underwear once the heavy bleeding is done.

What brands did you use?

Did they work for pp bleeding?
