A positive ovulation test on day 17 of a 27 day cycle can point to a short luteal phase, meaning there are fewer than 11 days between ovulation and a period.
🔹️This matters because the luteal phase is when progesterone supports implantation, so if it’s too short, this can make it difficult for implantation to occur.
🔹️At NeoFertility, we don't reccomend using ovulation tests in isolation, we reccomend using the app to create a fertility chart to really understand your fertility.
