Fatigue or feeling like you are tired is a common symptom of pregnancy. Some women describe this as a lack of energy or being lethargic. Your fatigue will not harm the baby in any way and it makes for a great excuse to take a nap.
What causes fatigue during pregnancy?
There is a combination of factors that contribute to your fatigue or lack of energy. First, there is a rapid shift of hormones that triggers several changes in your body. Your blood volume and circulation are both increasing. You have a developing baby and enlarging uterus. And, you have just the normally demands of day to day activities. All of these take energy and you only have so much to go around.
When do these changes occur?
Some people even report fatigue before they have missed a period. However, this symptom most commonly occurs in the first trimester around six to eight weeks.
How frequently do they occur?
The majority of women report fatigue in some sort of fashion. Usually the difference is found in the intensity or duration of fatigue. Some women feel bouts or momentary fatigue where others report feeling sluggish all day long. It is common for fatigue to be experienced throughout your pregnancy.
