need pregnancy advice

I'm 39 weeks tomorrow and last few days my feet and hands have been swollen more then normal and I get heat flashes in my face and always tired and don't have the urge to do anything. Everyone keeps telling me it can be signs of labor cause I lost my mucus plug and having the odd cramps but I don't know what to think I just donT feel right. Plus if I call the hospitial (don't have my own doctor) they make it seem like nothing
