Should I test?

So I have somewhat irregular AF and pretty long cycles (anywhere from 33 to 35 days usually). I got positive OPK this month so I have a good idea of ovulation. So I would be about 11 dpo right now... glow calculations are saying period is due 30th (about 3-4 more days), some other apps i have are saying 27, 28 or 29 as well. I'm just kinda curious as to whether I should test in the morning or wait longer? I'm aware that the longer I wait, the more accurate the result would be, but wondering who all has tested at this point in time and got a positive. Thanks!
