If My Due Date Is March 14 2010 When Exactly Did I Conceive?

You conceived on Jun 21, 2009. I am due on March 14, 2010. And I used Ovulation test to track my date. Mine was Jun 21, 2009.

Your estimated due date (EDD) is 40 weeks after the first day of your last period. On average, women's cycles last 28 days, and they ovulate about 14 days before their period starts. Conception occurs within a day or so of ovulation. So if you're average in all these ways, then you probably conceived about 38 weeks before your due date (just count back on a calendar), count forward two weeks from the first day of your last period. But some women have different-length cycles, or ovulate at a slightly different time in their cycle. So this is just an estimate.
