When can I test?

[TTCnumberfour]

I’m currently on CD21 of a 27/28 day cycle i apparently ovulated on CD 15/16. When is the earliest I could test? Got some Frer coming today.

They always say for am accurate result to test day after missed period. But this time I got a positive on 10DPO that was very clear, that was CD23 for me ovulated CD13.

With my first I didn't even get a faint line until CD29 but I wasn't tracking ovulation then x

With the FRER tests they say you can test up to 6 days early, which is 6 days before your period is due, which would be around CD22 from what you've said. The line can be really faint this early though, which can play tricks on your mind (it is a line, can I see what I see or am I making it up?? type thoughts) so it's always worth leaving it a little later if you can to be really sure. Best of luck! xx
