28 weeks , anyone else ?

So I am in my 3rd trimester . My 1st was bad I had no sickness at all but I ate all day everyday , my 2nd I controlled it actually lost my appetite and was okay now my 3rd trimester I am so dam hungry , all the time & tired , when I do have energy I spend it organizing and deep cleaning , but my question is , is this normal ? To be so tired and so sleepy. It's unbelievable ? Thanks in advance
