Starting to feel swollen but not really visible

My feet have been hurting for like 4 days now like if they are swollen but to me they don’t really look it. But it hurts to stand on them and my hands have a weird feeling too like when I bend my fingers and wrist they feel a bit swollen but don’t look it. Ugh anyone else starting to feel different ? 32 weeks pregnant. House chores are getting really hard my back is starting to hurt almost all day now. I can barley walk because of it, the pain goes from my lower back to my legs.
