There is no point testing immediately after ovulation as it takes time for the egg to implant. Wait for at least 12 to 14 days after ovulation, or simply test on the day of your missed period.
Clinically, implantation happens 6 to 12 days after ovulation, and then hCG starts releasing. My doctor told me that testing before 11-12 days past ovulation is usually inaccurate, so wait a bit.
I remember counting every single day after ovulation, it felt like years! Honestly, testing around 12-14 days post-ovulation is best, so hang in there, your patience will pay off.
Put down the test strips, girl! Testing immediately after ovulation will only show one lonely line and give you stress, wait at least 12 days or till your period is late.
