Maybe, but: Counting back 40 weeks should put you at the first day of your last menstrual period - that's when the counting is started, because it's the only (usually) reliable 'marker' or sign your doctor would have (because days of intercourse will vary for most patients, and be hard to remember) but most patients will be able to recall whentheir period occurred, and then the day of ovulation/expected concp.
