A member asked:
I had an ultrasound on dec 17 it says i was 11weeks and 4days. when did conception happen? october 15th?

9 weeks 4 days ago: Pregnancy dating is based on menstrual dating - so a pregnancy at 11 weeks 4 days would actually be 9 weeks and 4 days after conception occurred. You can do the math from there.

Oct 11: October 11 if the cycles are regular and 28 days apart. If the cycles are every 30 days then oct 13.
