Sleepiness in early pregnancy is a normal reaction. After pregnancy, usually around 6 weeks after menopause, pregnant women will experience morning sickness, sleepiness, fatigue, nausea, aversion to oil and acid reflux, which are collectively referred to as early pregnancy reactions. The early pregnancy reaction is related to the increase of hormone levels. The chorionic gonadotropin level in the mother’s body increases after pregnancy, and reaches a peak at 9-10 weeks of pregnancy. By the 12th week of pregnancy, which is the middle of pregnancy, the chorionic gonadotropin level will decrease, and the early pregnancy reaction will be significantly reduced at this time. Therefore, it is normal for pregnant women to be sleepy in the early stage of pregnancy, but usually after this stage, in the middle of pregnancy, this feeling will be significantly reduced, and they will not be so sleepy.
