The gynecological examination is a mandatory part of a woman’s checkup. The gynecological examination is required to know the condition of the cervix and vaginal discharge. In addition, an ultrasound is also required. After menstruation, the hormone level, vaginal environment and cervical condition are generally more stable, so it is better to have the examination at this time. It is recommended not to have sexual intercourse or use vaginal plugs for 2-3 days before the checkup. This is because the vaginal environment may change due to the infiltration of semen and the stimulation of medication, which may lead to inaccurate test results and conceal the true condition. Therefore, it is important to take proper care during the three days before the test. In addition, when there is bleeding, it is not very suitable for gynecological examination, but of course, it depends on the specific situation. A little bleeding usually does not affect, and a lot of bleeding temporarily does not do gynecological examination.
