The most common reasons for vaginal bleeding with lower abdominal pain in the early stage of pregnancy are as follows: firstly, due to pre-eclampsia, when there is insufficient progesterone or over exertion, the gestational sac and the uterine wall are peeled off, which will lead to vaginal bleeding and lower abdominal pain. Clinically, if the embryo is still developing well through examination, the treatment can be actively given to stabilize the fetus. Secondly, due to localized cervical lesions, such as cervical polyps, clinically because the polyp tissue is relatively brittle, so it will lead to bleeding phenomenon, because the local bleeding may also lead to lower abdominal pain. It is recommended to actively give appropriate clinical treatment, such as cervical polyp excision surgery, and be sure to send the excised polyps to the pathology laboratory, clinical diagnosis based on pathology.
