When did I conceive The sonar measured...

Hi Doctor,
The sonar measured the baby and currently 9weeks and 4days. Thing is I would like to know when i conceived. I had sex on the 26, 27, and 29 of february but I also had sex on the 19th and the 21st of February. I took a pregnancy test on the 09 March and it was negative took one on the 22nd March it was positive. I started getting signs the week 15th March. Does Measuring the baby give the exact day of conception if one counts back? I have a very irregular period which is about 39 days, have missed a month once. I last had my period on the 23rd of Jan. I need to know if conception happened by the 19th or by the 26th? Thanks

The scan date is what is called the gestational age. To find the conception date, cont Bach the gestational age minus 14 days. So 7 weeks 4 days from the scan date. These dates are accurate to within 3 or 4 days at this stage.

I think this date is around March 3 ( you do not say what day you had your scan).

So it is by far the most likely that Mr Feb 26,27,29 got you pregnant.
