It looks like a vet visit and a good medicated bath, which will both clean her up and be a start on treating the rain rot and mud scald, are in order. Then lots of groceries and you'll have yourself a nice little horse or two! :)
Rain rot can be because of an infection or rain, but a poor diet and stress including pregnancy can definitely bring it on as well and make it tough for the horses to fight off. You want to get her clean and dry as quick as possible, and it might take weekly bathing with medicated shampoos (lots of different kinds, the easiest is to just mix iodine/providine into your shampoo of choice) to get started. Sometimes adding extra vitamin A can be helpful, but in her case, it's probably something you need to go over with the vet since I don't know if there are any effects on gestation or foaling.
