How soon after taking dydrogesterone tablets following ovulation induction can pregnancy be detected?
After ovulation induction, taking dydrogesterone tablets usually allows pregnancy to be detected in about 10 days. The specific analysis is as follows:
Taking dydrogesterone after ovulation induction can increase the chances of conception. Fertilization typically occurs within 1–2 days, and the resulting embryo normally implants into the endometrium 6–7 days later. After implantation, trophoblastic cells form and begin secreting human chorionic gonadotropin (hCG), which can be detected approximately 10 days after ovulation. Pregnancy can be tested using a urine pregnancy test strip; two lines indicate pregnancy. Alternatively, serum hCG testing can confirm pregnancy, with significantly elevated hCG levels indicating successful conception.
If pregnancy does not occur after taking dydrogesterone following ovulation induction, withdrawal bleeding typically occurs within 3–7 days, indicating failure of embryo implantation.
