After the delivery of women, the reexamination showed that the uterine volume was too large, which may be due to the formation of excessive fibrotic tissue during the recovery of the uterus, affecting the normal repair of the uterus. Generally, the uterine volume is too large to affect normal pregnancy, but there is another case that the focus of adenomyosis appears during the repair of the uterus, which can cause dysmenorrhea and infertility, and some women will also have increased menstruation. If the amount of long-term menstruation increases, leading to hemorrhagic anemia, you can start taking Gongxuening orally on the second day of menstruation to reduce the amount of bleeding and avoid hemorrhagic anemia. Pay attention to observe whether there is dysmenorrhea. If there is dysmenorrhea, recheck the ultrasound in time to see whether there is adenomyosis or small hysteromyoma.
