How soon to test with a FRER?

[css04]

Hi - exactly that...how soon would show results with a First Response pregnancy test?

My AF is due on 8 Aug and I ovulated around 28 July.

I can't remember how soon I tested with my DC1 but I know I got results before my AF was due.

Thanks

I think it's 6 days before your missed period, so 4th Aug for you. But I wouldn't bother until 10dpo unless I was getting symptoms.

@weathervane123 thanks! Yeah 6 days before period doesn't make sense as I have quite a short luteal phase.
10DPO sounds about right
