How long after ovulation can pregnancy be detected with test paper

If about 20 days after ovulation, you can test whether you are pregnant by early pregnancy test paper. However, due to the relatively short time, it is recommended that you stay in the morning urine for testing. Because the HCG concentration in the morning urine will be slightly higher, the positive rate will be higher using morning urine test. If the first test shows a negative result, it is recommended that if there are no symptoms, you can do an early pregnancy test after 3 days or 5 days, or do a blood HCG test, so that the sensitivity is higher. If you check again, it is still clinically negative. It may be true that you are not pregnant. You can wait for menstrual cramps.
