The lining of the uterus will be of different thicknesses at different times, and the most accurate time to examine it varies according to the purpose. If you want to see if the lining is suitable for pregnancy, you need to observe it during the luteal phase, and if you want to determine whether the endometrium is overgrown or not, you need to observe it during the follicular phase.
When a woman wants to prepare for pregnancy, she needs to judge whether the thickness of the endometrium is conducive to the implantation of a fertilized egg by the thickness of the endometrium, and at this time, it is recommended that the examination be conducted during the luteal phase, that is, about a week before menstruation;
When a woman has endometrial polyps and excessive endometrial hyperplasia, she needs to rule out physiologic endometrial thickening, and the most accurate test is conducted during the follicular phase, i.e., just after menstruation.
When a woman suspects that there is a problem with her endometrium, it is recommended that she go to the hospital in a timely manner to have the thickness of her endometrium checked under the guidance of her doctor.
