Hi,
Well first of all are you taking any other medication? Because your signs could be the side effects of a medication you're taking.
Another simple reason could be
dehydration, are you drinking enough water?
The smell can be cause of a variety of reasons, for example cause of something you ate.
Another more serious reason of dark urine can be because of blood in your urine. It won’t be as obvious as a bright red drop in the toilet, but it could be a sign of bleeding higher up in the
kidney which could indicate an infection, kidney disease or even cancer.
So drink more water and if your urine lightens in colour you dont need to worry, but if it doesnt well get a urine analysis is done.
And the last thing which may very well be the reason for all these signs, is that you're pregnant and you just dont know it yet, so get a home
pregnancy test and check it out.
So in this order check the things off -
side effect of other medication
pregnant
dehydrated
I hope this answered your question.
