A member asked:
I had a dating ultrasound on 4/19 dating me at 9 weeks 4 days with a due date of 11/18. my lmp was 2/14, could i have conceived from intercourse on 2/21?

Yes: Typical ovulation occurs 14 days after the first day of your menstrual cycle. Since the ultrasound was at 9 weeks, it is accurate +/- 7 days.

Is possible: Based on your dating ultrasound, your estimated date of conception would have been 2/26. This assumes a regular 28 day cycle and ovulation on day 14 of the cycle. If you know for sure your first day of LMP was 2/14, suggests ovulation 2/28. These are estimates based on assumptioms, but the dates are close enough that it is possible you could have conceived 2/21.
