Ten days after a period is the optimum time to conceive. So 2 weeks is about right. Congratulations.
1 month and 2 days.
5 weeks and 2 days before that day - give or take a day or two.
99% probability it was between 10 weeks & 10 weeks and 4 days ago.
About 6 weeks and 2 days.
Your hunch is right; the ultrasound date is based on the day your last period ended. So, on average, the 40 week pregnancy begins two weeks before conception has even occured.
31st March or thereabouts
You conceived 4 and 1/2 weeks before you wrote this question. Check your calendar to see the exact date.
