when should i test?

Hi, Ovia has predicted my period to be in 3 days but i can do a pregnancy test in 7. P tracker says 3 days and to test in 3 days. Glow says 7 until my period.. i know i should just stick to 1 tracker, but when should i test? Im 7dpo today (i ovulated late) which is too early to test (however i feel sick, headache and got a belly ache)
