Fig. 3.6 Development of placental blood flow. Left column: Typical 3-D Power Doppler scans from placentas of normal pregnant women at weeks 18, 24, 34 and 38. The flow signals within placental villi (white arrows) increase in extent, intensity, width and height with advancing pregnancy. At term (38 weeks) tree like structures can be visualized. Since only anterior placentas have been used for these scans, the uterine wall (UW) is always at the top of the scan while the chorionic plate (CP) is always at the bottom of the scan.

Adapted from drawings of Peter Kaufmann, Aachen, Germany.

Pregnancy Diet Plan

The first trimester is very important for the mother and the baby. For most women it is common to find out about their pregnancy after they have missed their menstrual cycle. Since, not all women note their menstrual cycle and dates of intercourse, it may cause slight confusion about the exact date of conception. That is why most women find out that they are pregnant only after one month of pregnancy.
