So im still confused on if you dont member your lmp when you get an ultrasound how come they still tell you to subtract two weeks away from the weeks and days they give you on your ultrasound to find possible conception?
Most women ovulate at about the middle of their cycle. Due dates are based on you last period, which is generally in the range of 2 weeks before conception. There for, technically, you're considered 2 weeks along at the point of conception, and usually about 4 weeks by the time you miss your period.
yes the baby is 11 weeks plus growth wise but u are 13 weeks pregnant they count in pregnancy the week of youir period to the moment of conception so according to the charts you are 2 weeks pregnant before you concieve i dont know why LOL
