Unless an individual woman ovulates really late into her cycle, at 3 weeks of pregnancy, conception would have occurred. Some women who ovulate late into their cycle may conceive around this time. For women who have already conceived, the baby is still just a ball of cells called the blastocyst; and those cells are multiplying rapidly at this time.

Women are unlikely to feel any real symptoms of pregnancy even in this week. If you took a pregnancy test right now at three weeks of pregnancy, it will be negative in all probability, even if conception has actually taken place. There are some major hormonal and other upheavals ongoing inside the body right now, but you’re probably feeling nothing.

Changes in the baby

When sexual intercourse occurs, the male sperm travels up the vagina, through the cervix and on to the fallopian tubes where the egg and the sperm meet. The fertilized egg is in the fallopian, where the cells will start to multiply in about the third week of pregnancy.

  • Still just a cluster of rapidly multiplying cells, the blastocyst now begins the journey from the fallopian tube to the walls of the uterus, where it will embed itself and start to draw sustenance from the mother.
  • Once implanted in the uterus, the placenta will also slowly start to form. The amniotic sac and the amniotic fluid will also start to form which will help protect the baby until he or she is ready to be born.

Changes in the mom to be

When you are 3 weeks pregnant, there are still probably no real or palpable changes in the mother, though internally there is much activity.

  • It is likely that the mother to be is feeling some amount of anxiety and trepidation about impending motherhood, particularly for first time mothers who may wonder how they will ever manage to look after a baby!
  • The dad to be is also probably feeling some amount of trepidation and excitement as well, at the new life that he helped create.

Tips for the 3rd week

For week 3 of the pregnancy, mother to be and dad to be should continue to be as healthy as possible, giving up bad habits, eating healthy and exercising regularly.

  • Eating healthy is important for both parents because the nutrition that the baby gets early in life, could have a bearing on his or her health later.
  • Continue to take your folic acid and follow any instructions given during an antenatal checkup.
