Bleeding at 8 weeks of pregnancy can be caused by pre-eclampsia, ectopic pregnancy, combined vaginal and cervical lesions of pregnancy and external irritation. 1.If you have been seen in the hospital and the pregnancy is clearly intrauterine, vaginal bleeding at 8 weeks of pregnancy without abdominal pain or vague abdominal pain, there is a possibility of pre-eclampsia, and you need to seek medical attention in time. Pre-eclampsia should be considered after gynecological examination except vaginal and cervical lesions. The external causes include external impact on the abdomen, intercourse, etc. The internal causes are often insufficient hormone levels (HCG or progesterone), autoimmune system diseases, embryonic chromosomal or genetic abnormalities. In this case, the blood HCG and progesterone levels should be rechecked and the early pregnancy ultrasound should be repeated. If the ultrasound indicates normal embryo development, but the trend of blood hormone level growth is unsatisfactory, the pregnant woman should rest in bed and take oral fetal preservation drugs, if there is no relief, progesterone type drugs can be injected intramuscularly for fetal preservation treatment; if the ultrasound indicates embryonic abortion and the blood hormone level is lower than before, consider inevitable abortion and need to carry out uterine evacuation as soon as possible. 2.If there is no clear intrauterine early pregnancy in the past, only positive urine test paper at home, bleeding at 8 weeks of pregnancy does not exclude the possibility of ectopic pregnancy, should promptly go to the hospital for examination and clear diagnosis, if accompanied by obvious symptoms of abdominal pain, more immediately in the nearby hospital for consultation. Blood HCG and vaginal ultrasound should be checked and if the result shows ectopic pregnancy, surgical treatment is mostly needed. 3. In conclusion, regardless of the cause of vaginal bleeding at 8 weeks of menopause, you should seek medical attention promptly, especially for pregnant women with undetermined intrauterine pregnancy, and be alert to bleeding caused by ectopic pregnancy.
