Signs of oncoming labor?

Yesterday I started feeling a bit more pressure in my bladder than usual and noticed my face has broken out over the past couple days. Today it feels like my bladder is overfull and ready to pop even though I keep going to the bathroom, I've also thrown up and am feeling quite a bit of pressure in my rear end as I stand/walk. FTM so completely new to everything, I also have my 37 week appointment tomorrow so I will mention all of this then but I'm curious as to if these might be signs that labor is going to be starting soon (like in the next week or something) or if it's all just a coincidence. Any insight is greatly appreciated!
