Under normal circumstances, if you are pregnant and have bleeding during pregnancy, the baby will be fine, but most of the bleeding will be due to cervical problems. Cervical problems will appear a small amount of bleeding, or blood in the white blood, usually does not affect the development of the fetus, so the child is not a problem, after delivery must go to the hospital to do cervical examination, do cervical cancer screening. Generally, TCT and HPV are the two tests for the cervix. TCT is also called thin layer liquid-based cytology and HPV is also called human papilloma virus test, through which the cervix can be initially screened for cervical cancer and precancerous lesions. To rule out cervical cancer and precancerous lesions, if you keep bleeding during pregnancy, you can’t rule out bleeding caused by cervical polyps and cervical erosion, so if you keep bleeding and the baby is still fine, you should consider that the cervix is more likely to have problems.
