Gestational age- starts with the first day of the mothers last menstrual period. Fetal age- starts with conception. Since conception is almost never known doctors and midwifes in the u.s. talk about a woman's pregnancy using gestational weeks because its much easier to identify the first day of the last menstrual period, than actual date of conception. So you're already considered 2 weeks pregnant from the moment you conceive. On average a woman has about a 28 day cycle with a 14 day lutheal phase, which means most women will conceive their baby approximately 2 weeks after their period.

My ultrasound today showed the baby at about 6.5wks. Based on my LMP I should be 8wks pregnant. We saw a strong heart beat. What does this mean?
How far along you are based on your LMP is called Gestational Age. Technically, in this method, for the first two weeks of your pregnancy, you aren't technically pregnant. What you found out at your sonogram was called Fetal Age, this is the actual age of your baby since conception. Conception usually happens two weeks after the first day of your last menstrual period so your sound like you are right on track.
