There can be lots of reasons for this Karen, not least of which what you eat. E.g. beetroot can strongly colour your urine and eating aspargus - I'm sure you know the smell if ever you've eaten them.
You might have an infection but usually that is accompanied by other symptoms also e.g. pain (stinging or burning) on passing urine, constant feeling of needing to pass urine, difficulty starting to pass urine, fever, generally feeling unwell, nauseous to mention some of the main ones.
There could also be blood present in the urine to make it redish - which of course would not be good news.
I'd avise you to check with your doctor, especially since it's been a few days
