When can I take a pregnancy test?

Question

Accepted Answer

This site estimates the recommended testing time based on Wilcox NEJM 1999. From your estimated conception date, blood hCG test is reliable about 11 days later and urine pregnancy test about 14 days later. Blood hCG is a quantitative test at a clinic — earliest and most accurate. Urine tests at home are reliable around the missed period. Ovulation and implantation vary by ±2–3 days, so retest in 1–2 weeks if negative. For confirmation, see an obstetrician.
