Pain in foot?

This is weird.. but I am almost 34 weeks and I just started getting this shooting pain on the top of my foot.. it goes up my leg when I walk - I haven’t bumped it or anything, it’s almost like a stabbing pain. Normally, I wouldn’t be concerned, but I’m nervous it might be a blood clot?? Maybe a pinched nerve? Has anyone had this? Or know anything about what might be going on
