The possible reasons for more bleeding after taking the biochemical pills for unclean discharge include poor uterine recuperation, infection or uterine residue. Under normal circumstances, postnatal discharge lasts for 4~6 weeks. If the postnatal discharge continues to be unclean, it is recommended to go to the hospital where you gave birth or the obstetrics and gynecology department of the local regular hospital for further gynecological ultrasound to understand the size of the uterus and to clarify whether there is any residue in the uterine cavity, as well as further gynecological examination to find out whether there is any foul smell of the discharge, and whether there is any uterine pressure and pain. If there is residue in the uterine cavity, you need to do further hysteroscopy to clean up the residual tissue; if there is an infection, you need to follow the doctor’s instructions to reasonably apply antibiotics; if the uterus is poorly restored, you need to give uterine contraction agents as soon as possible. Therefore, if the evil dew is not clean take biochemical pills bleeding more, it is recommended to timely go to the hospital for examination, and follow the doctor’s instructions to deal with treatment.
