This can be caused by numerous things. I will give a few examples of which one will probably immediately ring true for your particular case. If not, give it a few weeks and if it doesn't go away contact your GP. Dysgeusia is the medical term for a change in your sense of taste and could be described as a perfume or metallic taste.
Possibly the most common cause of a completely unprovoked taste in the mouth, is pregnancy. What causes this taste is hormone level, and in particular oestrogen. When you're pregnant, oestrogen levels change and your sense of taste may also fluctuate widely. Many people experience this symptom in their first trimester and unfortunately it is difficult to get rid of in this case. It will also tend to get worse after you eat or drink.
Similar to that above, anything else which may alter hormone levels may also have this affect, for example starting to take a contraceptive pill. In addition to this, some other medications have a similar side effect, most commonly antibiotics. Most courses of antibiotics will run for about a week and so during this time and for a few days after you stop taking them, you may have a strange taste in your mouth and even a fuzzy tongue.
Other examples could include anxiety, as you may experience drying of the mouth alongside altered hormone levels; taking strong flavored vitamins or supplements, as these often have a lingering taste which you don't notice at first as you will swallow them whole; spraying air freshener in your house, as your nose will get used to the smell but it will still be floating in the air and getting into your mouth.
