Toe pain!

Im 37 weeks and I really think I may have a fractured toe, due to weight gain?? Over the past week it's been hurting when I walk, but tonight it is so much worse. My app says i walked 5 miles today and of course my whole body is in extreme pain, but that toe, ohhhh it hurts so bad I can't even wiggle it. I'm nauseated from the pain. I haven't stubbed it or anything just noticed pain when walking (after today it is now constant). Anyone else have/ or have heard of this? What do I do? Hellllp!
