Unprotected sex before ovulation

I had unprotected sex on the 2nd and 3rd of jan and according to glow my ovulation starts on the 6th of jan.

For some reason glow isn't showing my next due period but it's supposed to be between the 23rd-25th.

I had a really bad miscarriage October last year at 10 weeks (was measuring 4) so I don't no if my ovulating dates will be correct now.

Is there any chance I got be pregnant again? I remember my CM was real thin and milky on the week we had sex.

I don't have any bad symptoms apart from fatigue and a tinyyy bit nauseous today.

What do you think?
