Bigger socks for swelling?

I started swelling a bit a few weeks ago & my biggest problem is that my socks are too tight & they leave marks on my legs. I thought getting men's socks would help since they're bigger than women's, but even though they are looser, they're still digging into my skin. Any suggestions? I'm not a big girl, either, so it makes me wonder how women who normally have thicker legs deal with this /: Is there anything I can do? Only a few weeks left till baby is born, so I've been trying to deal but idk if I can anymore! Is there such a thing as "plus-size socks"? Haha
