The optimal time to take a home pregnancy test after IUI depends on several factors, including the sensitivity of the test and individual hormone levels. Generally, it’s recommended to wait until at least 14 days after ovulation or 12 days after IUI to ensure accurate results. This allows sufficient time for implantation and the production of detectable levels of the pregnancy hormone, human chorionic gonadotropin (hCG). However, using a highly sensitive test may allow for earlier detection. It’s important to consult with a fertility specialist for personalized guidance and to address any specific concerns or questions.
