If you are more than 4 months pregnant and you have a slight redness, that is not normal. At this time, you need to go to the hospital immediately for examination, because placenta praevia, low placenta, cervical inflammation, cervical polyps and also precancerous lesions of the cervix and cervical cancer may cause a small amount of vaginal bleeding, so you must go to the hospital as soon as possible for ultrasound examination and vaginal examination. If it is seen that the placenta is low or placenta praevia, the bleeding may be caused by this, then it is important to take rest and apply fetal preservation medication. If the bleeding is caused by chronic cervical inflammation or cervical polyps, anti-inflammatory treatment is needed. At this time, pre-cancerous screening of the cervix can be done, and if the result of the screening is not cervical cancer, temporary observation is sufficient.
