The most important thing to do is to have a gynecological examination to find out where the bleeding is coming from if you are pregnant and have blood in your leukorrhea. If the gynecological examination reveals that the bleeding is coming from the cervix, further examination is needed to clarify whether the bleeding is caused by cervical inflammation or cervical polyps, or even cervical cancer. If the bleeding comes from the uterine cavity, further tests, such as ultrasound and blood sampling, are needed to clarify the development of the child’s embryo, and to clarify whether there is a pre-eclampsia, embryonic dysplasia, ectopic pregnancy, or fetal arrest. Therefore, gynecological examination is the most basic examination, but also through certain ultrasound, blood sampling to clarify the development of the fetus, so as to understand what exactly is the cause of blood in the leukorrhea during pregnancy, and then treat the symptoms, so as to be able to solve the fundamental problem.
