Pregnancy Encyclopedia – Understanding Week 1

For most women, week 1 goes by without realizing the pregnancy exists.  Monthly cycles vary for women. Hence, most women assume that a delay in monthly menstrual cycle is just a delay. There aren’t any instant pregnancy symptoms during the first week that may make a women wonder about the delay. However, one may experience mild signs such as tiredness, mood swings, fatigue, loss of interest in things, and even consistent urge to urinate. These signs are quite similar to PMS. So women don’t really suspect pregnancy.

Baby Development

This first week is actually the menstrual period of a woman. Since the expected delivery date is calculated right from the first day of last period, the week counts as an integral part of 40-week pregnancy although the baby hasn’t been conceived yet.

Mother-to-be’s Body

As already discussed, no obvious physical changes occur during the first week. However, the mother’s body experiences a number of internal changes.  Common signs include the following listed below:

  • Digestive problems like nausea, gas, and constipation
  • Tender breasts
  • Fatigue
  • Mood swings
  • Morning sickness
  • Hormonal changes

The above mentioned signs and symptoms vary from woman to woman. It is important to note that most women don’t feel these changes until after the second week.  Most doctors recommend the first week of pregnancy as the “carefree week”. Women are allowed to enjoy same dietary and physical habits.

Week 1 Pregnancy Tips

In case, you are planning pregnancy, the first week may be a sign of joy.
