Absolutely, get her checked if you can rule out a urinary tract infection,then you know it is behavior orented.Don't bother getting up set at her she must learn, which means, she needs to be taught, and you cannot teach if you are upset.Keep her with you when she is not in the crate. Where is the crate being kept? Do you hear her at night if she has to go out? If not the crate needs to be closer to where you are. I'm training a 15 week old and she is picking it up fantasticly but I have her set up differently than most.She is in an excercise pen,actually ,2 hooked together,so there is enough room for her to move around and play,there are minimal amount of newspapers down in case of an accident,a large crate keeps the exercise pens from moving when she jumps up at the sides.She is in there to eat and sleep at the moment.When she is let out she goes right to the door(a bit of a trek from the family room) where I put on her leash and collar we go outside if she has to go she does if after a few min.she hasn't gone we come in but stays where I can see her.In about 10 min.we go back outside and she will usually go. Then she is good for thirty min.or so,she plays,then I might put her back in the pen to take a nap so I can get something done around the house.That is how it works all day long ,so far no bm's in the house one accidential pee,since she was 13weeks old. A Labor of love.
