It’s pretty normal during pregnancy to get swollen feet and it’s almost inevitable. You can elevate your feet whenever you can, drink more water because the lesser gou drink the more your limbs are trying to retain water, wear compression socks. For comfort, don’t wear tight shoes. Just go with slippers. I went to work with birkenstocks when my feet started swelling.
You can mention to your gynae but i doubt they can or will do anything because it’s really normal to get swelling limbs during pregnancy
