A member asked:

I'm confused with my conception date i was told by an ultrasound that i concieved on the 13th of october 2013 but had sex on the 4th of october?

Conception date more accurate: Your conception date is more accurate if your menstrual cycles are regular. Ultrasound findings have a range of growth variability related to date of pregnancy. I would go with date of ovulation and intercourse versus ultrasound dating.
