If a pregnancy keeps bleeding, it is necessary to determine whether the fetus can be saved based on the amount of bleeding, the degree of pain in the lower abdomen, and the dilatation of the cervical opening. If you have been bleeding after pregnancy, and the amount of bleeding is small, only accompanied by a slight pain in the lower abdomen or no pain, and the cervical opening is not dilated, then it may only be caused by preeclampsia, and it is possible to save the fetus through oral progesterone and other treatments. However, if the bleeding is heavy, or even there is tissue mass outflow, and accompanied by paroxysmal severe pain in the lower abdomen, and even the cervical opening is dilated, then it may have already reached the stage of inevitable miscarriage, and at this time the fetus may not be able to be preserved. Pregnant women once found their own pregnancy has been bleeding, must promptly seek medical attention, under the guidance of the doctor to improve the relevant examination, if you need to use drugs should be under the guidance of the doctor to use drugs, to avoid accidents brought about by the drug, do not blindly use drugs.
