Ankles and lower leg swelling @ 6 weeks??

I’m 6 weeks pregnant, and taking progesterone. Today, I noticed moderate swelling in my ankles and lower legs. I don’t remember it starting this early with my first. Anyone experience this early in pregnancy? Or as a side effect of the progesterone? Or something else?

I will talk to my doctor, obviously, but I don’t want to worry all night over it. I’m already a mess with anxiety, and google is not helping it. 😳
