Help pls ovulation date confusion

So I had my periods on the 27 of June and finished on 29 and then glow showed that my peak day was 11 so I started checking my LH surge from 10 onwards and it's the 13 today's and no LH surge as yet no positive line, Iv had sex everyday from 30 except the 8 and 9, could it be that I missed my ovulation date and if I did is it still possible that I get pregnant despite not having sex on the 8 and 9 or is it possible that my ovulation is late and i should keep checking? Pls help
