Okay so from that with a 28 day cycle and ovulating CD15 ish and 24 days cycle ovulating CD12 ish probably means your luteal phase (phase after ovulation) is usually 12/13 days.
So whenever you ovulate, regardless of whether is CD12 or CD15 you’re period should be expected 12/13 days later. So your right in thinking by that as you ovulated a bit earlier this cycle, you are likely to have a cycle length which is shorter more like 24/25 days this month.
But for testing “6 days before period” which is states on these tests obv cannot relate to each individual as our cycles and luteal phases are all diff lengths. So it uses a standard cycle and it’s where they get there stats from.
So a standard cycle is ovulate day 14. 14 day luteal phase and 28 day cycle. So AF shows up 15dpo on CD29. That is what clearblue and any others will use in testing and stats etc as they can only do it based on a standard cycle.
So for example, the fact it states can determine a pregnancy 6 days before expected period date. “Period day” for that reference is 15dpo. So it’s saying it can detect a pregnancy earliest at 9dpo.
Your luteal phase is shorter by a day or 2. Still a normal length. But therefore you can’t test 6 days before your period because it’s too early. Cos that makes you 7dpo. Does that make sense?
So realistically every single person needs to wait until 9dpo for those tests to use. Regardless of when there period is due. Can’t use the period as such need you need to go by days past ovulation.
So hence prob still too early for you to test. And the percentage of positives on 9dpo is only like 30% ish. And by day of expected period at 15dpo 99% would be positive.
Lots of period assume they can go by there own period etc but it isn’t actually what it means it means expected period of a standard cycle and 14 day luteal phase. if you don’t have a 14 day luteal phase you need to adjust the days etc to be relevant to you
🤣🤣🤣🙈🙈 I hope I’ve explained that well an it makes sense?
