AnswerIf your last period started on March 17, and you have a 30 day cycle (from the first day of your period until the first day of your next period), ovulation occurred on cycle day #16 (April 2) and you could have conceived if you had unprotected sex on April 1,2,3, or 4. The only accurate sonogram that you had was taken at 19 weeks 2 days on August 3. Your due date based on your last menstrual period is December 24. Remember, you can deliever two weeks prior to your due date or two weeks after your due date. Ignore the earlier sonograms because the error is too great prior to 20 weeks.
