Swelling??

If its water retention, you can tell by pressing parts of your feet & there’ll be a dent.. I didnt get major feet / ankle swelling during my pregnancy, so I kept to the same shoe size throughout..

I remember myself getting 1 or 2 size bigger for my shoes when I am pregnant. It's kinda obvious when you walk.

I think you'd be able to tell and feel.. When it's uncomfortable to fit into your shoes

Well... You will know cos you will feel it. Shoes may feel tight.

U cant fit into ur shoes and cant see ur ankles too

Check if you have any old photos and compare for reference.

Normally the shoe u are wearing will tend to be tighter
