One such relatively recent study tells us that implantation does not always take place on day 7 after ovulation. In fact it very rarely does. This study by AJ Wilcox (1) accurately determined the day of implantation by very sensitive pregnancy test (HCG) measurement compared to ovulation. HCG hormone starts being produced when the pregnancy implants into the uterine lining. The findings in normal women trying to conceive included: * first appearance of HCG (implantation) occurred 6-12 days after ovulation * 84% of the pregnancies implanted on days 8-10 after ovulation * early pregnancy loss increased with later implantation - implantation early pregnancy loss rate o 13% by day 9 o 26% on day 10 o 52% on day 11 o 86% on day 12 or more Overall the total pregnancy loss up to 6 weeks was 25%. Now that seems very high to most people but keep in mind many of these pregnancy losses occurred so early that women often were not aware they were even pregnant. The normal early pregnancy loss rate that most women know about is 15-18% of clinically recognized pregnancies so almost 40% of all pregnancy loss is unrecognized.
