12-24 weeks: Depending on the skill of the observer, many fetal abnormalities can be seen between 12 and 14 weeks. Optimal detection of anomalies requires an exam between 16 and 20 weeks, and the heart is best seen around 24 weeks. Genetic problems can be diagnosed with chorionic villus sampling at 10-12 weeks. Many fetal problems cannot be diagnosed at all before birth, however, even in the best centers.

Seven is seven: Seven weeks pregnant in a first pregnancy is counted the same way as in a second or third pregnancy. The method of counting doesn't change. Seven weeks is between 6 weeks and 8 weeks. Often, in developed countries, an ultrasound scan is done around 8-11 weeks to confirm the estimated dates for the pregnancy. Seven weeks pregnant usually means the last menstrual period started about 7 weeks ago.
