<human>: Ultrasound said I was 5 weeks 4 days on Sept 10. I had sex on Aug 4,6, and 17. I am very confused on which possible conception date it would be. Because I heard you take two weeks away from the ultra sound date? My last period was Jul 26 which means I should be further along right?
<bot>: Hi there, after reading your query, my opinion is that:1) The 5 weeks 4 days is counted from the day of your period, i.e. 26th July. So, you would be 5 weeks 4 days on 3rd September.2) The most likely date of conception would be 17th because there are chances of delayed conception as indicated by the disparity between your date and sonography.3) So, instead of ovulating on 10th, you would have ovulated a week late, on 17th.4) Most probable date is 17th in my opinion. Hope this answer was helpful.
