Could this be early signs?

Ok so I'm only 5 dpo. But been having odd things. Cramps at time bad. Could care less to eat some foods that I was craving two days ago. I feel tired just no energy or ambition to do anything. I'm frequently getting light headed with sudden movements or getting up. And some nauseousness but seems to happen later in the day? And I've been peeing none stop.  Thanks for any input 😉 when should I take a test?
