The sperm and egg may combine to form a fertilized egg on the day of intercourse. The fertilized egg is still in the germ cell stage, so the hormone level in the body has not changed at this time, so even if you are pregnant, the phenomenon of sleepiness does not occur clinically. Therefore, if you are sleepy, you need to find the cause, whether it is fatigue caused by too much stress, too much tension, too much work, or whether it is caused by anemia, or whether it is caused by low blood pressure. It is recommended to do the appropriate tests, such as blood pressure measurement and blood tests, to know if the sleepiness is caused by these reasons. And it is recommended that women should strengthen nutrition in their daily lives and eat more blood-supplementing foods that are more beneficial to their health.
