The excitement and anticipation in every woman's heart after pregnancy are unparalleled. It can be said that every moment after pregnancy is filled with strong curiosity. How old the fetus has grown and what the baby looks like now are topics of interest to expectant mothers. The fetus can be said to be the same every day, so how old does the baby grow in seven days of pregnancy for women?
Seven days pregnant, it is still just a small fertilized egg. Whether through early pregnancy examination or ultrasound examination, the fertilized egg cannot be seen yet because it is too small, it can be said to be a small cell.
Women need around 10 to 14 days of pregnancy to test for early pregnancy through changes in HCG levels in urine. It takes about 42 days for a woman to see the presence of a gestational sac in the uterine cavity through ultrasound examination.
At around four weeks of pregnancy, the fetal size is about 0.2 centimeters. At this time, the fertilized egg has just implanted and the amniotic cavity of the fetus has just formed, resulting in a very small volume. At five weeks, the fetus will swell to about 0.4 centimeters, and at this time, the amniotic cavity will enlarge, and the fetus's primitive cardiovascular system will appear with pulsation.
Therefore, in the first few weeks of a woman's pregnancy, the fetus is still very small, and most expectant mothers only begin to show obvious signs of pregnancy around 4 months after conception. From the appearance, it can be seen that the abdomen has already started to ache significantly.
