Seeing red is bleeding, and there are many causes of bleeding at 8 weeks of pregnancy, such as preeclampsia, ruptured ectopic pregnancy and cervical cancer. 1. Pre-eclampsia: If intrauterine pregnancy has been clearly diagnosed, the problem of bleeding at 8 weeks of pregnancy may be pre-eclampsia, which can be caused by insufficient hormone levels and chromosomal abnormalities in the embryo. If the ultrasound suggests that the embryo is normal, fertility preservation treatments, such as the use of dextroprogesterone and progesterone, can be administered. If it is caused by chromosomal abnormality of the embryo, abortion can be considered. 2. Ectopic pregnancy: If there is no clear intrauterine early pregnancy, only the test paper is positive, bleeding at 8 weeks of pregnancy may be ectopic pregnancy. If the examination found that the uterine cavity can not see the obvious gestational sac, but the uterus to see the mass, this situation may be due to ectopic pregnancy caused by bleeding. This situation needs surgical treatment, such as laparoscopic surgery. 3. Cervical cancer: patients with cervical cancer find pregnancy at the same time when they don’t know they have the disease, and bleeding occurs in the eighth week of pregnancy due to the invasion of blood vessels by the cancer. Conservative treatment or surgical treatment, such as cisplatin, carboplatin, paclitaxel, bevacizumab, radiotherapy, cervical conical resection, etc., can be chosen according to the specific conditions of patients. There are many other causes of bleeding at eight weeks of pregnancy, and many more treatment options, so it is recommended that such patients go to a regular hospital, consult with a professional doctor, and cooperate with the doctor to complete the relevant examinations to clarify the causes and avoid blind treatment.
