third trimester blues?

Not sure if this is really even a thing! 37+4 here and I can't seem to get a handle on my emotions. I'm irritable some days but mostly just sad- I find myself crying over nothing and usually starts right when I wake up in the morning. It will go away when I go to start my day try not to over think things but the sadness I feel at night and in the morning when I'm in bed is horrible! Most of the time when I cry I go to my SO for comfort and try to lay on his chest and sort of just want to cry it out but he's had enough and when I go near him if I'm even remotely upset he shrugs me off his chest and tells me to stay away that he can't deal with "me wanting to be babied all the time" . Is this something that is abnormal for me to be feeling/doing or is this just the end of pregnancy?? I'm starting to worry I'm the only pregnant woman who feels this way!!
