The exact management of a woman’s 15-day pregnancy is primarily related to whether or not the woman has a pregnancy requirement. If the patient has a pregnancy requirement, the patient may choose to continue observation. As long as there is no abdominal pain or vaginal bleeding, the patient may choose to repeat the ultrasound after one week, mainly to observe whether the patient is pregnant intrauterine or extrauterine. If the patient has abdominal pain or vaginal bleeding, the possibility of preterm abortion and ectopic pregnancy should be considered. The changes in blood chorionic gonadotropin and progesterone as well as the ultrasound need to be dynamically observed to determine exactly what is going on and then treated accordingly according to the results of the examination. If the patient does not have a pregnancy requirement, 15 days of conception is approximately equivalent to about 35 days of the patient’s pregnancy. In this case, it is too early for either a medication or an abortion, and the ultrasound may not yet be able to see whether the gestational sac is in the uterine cavity or outside the uterus. It is recommended that the patient should review the ultrasound after one week if there is no contraindication to medication abortion; if there is contraindication to medication abortion, abortion can be chosen.
