The exact treatment depends on whether the patient has a fertility requirement or not. If the patient has fertility requirements and there is no abnormal abdominal pain or vaginal bleeding the patient can be rechecked with ultrasound after 7-10 days to see if the patient is intrauterine pregnant. If the pregnancy is intrauterine and there are no abnormalities, the patient can continue to be observed and have regular checkups. If the patient is 30 days pregnant and has abdominal pain or vaginal bleeding, the patient should be considered to have a possible pre-eclampsia or ectopic pregnancy, so the patient needs to be dynamically observed for changes in progesterone, HCG, ultrasound and clinical symptoms. Pre-eclampsia can be treated with fertility preservation, while ectopic pregnancy can be treated conservatively or surgically depending on the results of the examination and the patient’s clinical symptoms. If the patient has no fertility requirements, it is not possible to determine whether the gestational sac is inside or outside the uterus at around 30 days of pregnancy, and therefore the abortion method cannot be chosen. Patients can have an ultrasound at around 40 days to determine if the pregnancy is intrauterine and if there is no contraindication to medical abortion, they can choose medical abortion first, and if there is contraindication to medical abortion, they need to choose abortion.
