33-36 day cycle

Some months i dont ovulate at all i had a small amount of ewcm cycle day 12 13 14 AF is due in 5 days im on day 29 or 30 i cant remember exactly but would it be too early to test? Usually i just know im not pregnant mostly because i didnt have any symptoms that i may have ovulated i think i might have this month i just dont want to test too early then deal with the disappointment
