Please help! Every since yesterday my feet, ankles, and even some of my leg have been really swollen and sore and since yesterday and today they look worse. I haven't been up on them a lot either and this is the first time they've gotten this big. Also I've been having on and off contractions through yesterday and today and hurt worse if I move and they'll move towards my back. They aren't a certain amount of time apart they're random. Should I be worried?
