Why Am I So Tired?
During the first phase of your menstrual cycle (the follicular phase), estrogen is the dominant hormone. It helps prepare the egg for releasing and to being fertilized. It also helps prepare the uterine lining to sustain a pregnancy. After ovulation (when the egg is released from the fallopian tube in preparation to be fertilized), the hormone progesterone takes over. This is what causes your temperature to rise after ovulation. It's also the 'feel good' hormone, the hormone which can help with sexual arousal in women, and a hormone that brings about a peaceful, sleepy feeling.
If you do not conceive a baby, progesterone drops sharply about 12-14 days past ovulation, which triggers your body to release it's uterine lining, which is your period. If you do conceive a baby and become pregnant, progesterone remains the primary hormone throughout your pregnancy. It causes sleepiness, tiredness, fatigue in pregnancy. Because of this surge of progesterone, you may find it difficult to make it through the day without a nap. Often, before you even miss a period, you'll feel sleepy and wonder if early pregnancy fatigue is the culprit.
Other Reasons For Fatigue
While being tired is an early pregnancy symptom, there are many other reasons you may feel fatigued or sleepy. Stress, depression, illness, lack of sleep, anemia (low iron stores), premenstrual syndrome, and dehydration can all be legitimate causes of fatigue.
As mentioned, feeling tired can be one of the first signs of pregnancy, but in addition to early pregnancy fatigue, you will also experience other symptoms such as a missed period. Always back up any pregnancy suspicions with a home pregnancy test (HPT). I recommend First Response Early Result (FRER). You can also visit your health care provider or midwife for a blood test, which is 100% accurate at detecting early pregnancy.
