Swollen Ankles like WOAH!

Hi all! 7w5d pregnant and I couldn't believe my eyes when I got home from work today (desk job with multiple walks up and down the hallway 2-3x/hour) and my fabric yoga sandals had made indents on my ankles and feet! 😮 I feel like it's pretty early to be having swelling like this. I'm also having some calf cramping during walks and have upped my magnesium intake which is helping a bit

Anyone else out there feeling foot puffiness or similar symptoms? I haven't even met my OBGYN yet - should I be worried?
