When performing the corresponding abortion or uterine evacuation, there is often a sensation of deep or shallow uterus. This sensation is mainly based on the different months of pregnancy and the different sizes of the uterus, which can lead to different judgments of depth. If the month of intrauterine pregnancy is relatively large, the uterus will be deeper and the uterus will feel deeper when performing the corresponding clearance or abortion, then if the month of intrauterine pregnancy is relatively early, the uterus will feel relatively shallow at this time. In addition, if the uterus is relatively large in the case of adenomyosis or fibroids, and the corresponding endometrial scraping is performed, the uterus may feel larger and deeper at this time, so there will be different judgments of depth in different cases.
