Does the endometrium thicken after the fertilized egg implants?

Patient's question:

No

Doctor's answer:

After conception, hormone secretion increases rapidly, and the endometrium is stimulated by hormones to thicken. However, if the time is too short, it may not be noticeable. This varies from person to person. Some people already have an endometrium of 10 to 12 millimeters during their ovulation period, so the thickening would be more noticeable.
