Introduction
Spontaneous abortion is generally not calculated from the day bleeding starts. If gestational age at spontaneous abortion needs to be determined, the date of conception is typically used as the reference point. For pregnant women with an unclear date of conception, the first day of the last menstrual period is usually used as the starting point for calculation. When determining the timing or duration of a spontaneous abortion, the time of gestational sac expulsion is typically used as the reference.
Natural abortion is generally not calculated from the day bleeding starts, as there are various symptoms associated with natural abortion. The details are as follows:
Natural abortion refers to the loss of a fetus due to non-artificial causes. Main clinical symptoms include vaginal bleeding and severe abdominal pain. When calculating gestational age for a natural abortion, conception date is typically used as the reference point. For women who cannot determine the exact conception date, the first day of the last menstrual period is usually used as the starting point. To determine when the miscarriage occurred or its duration, the time of gestational sac expulsion is generally considered the key reference.
Medical attention should still be sought promptly after a natural abortion to check whether any fetal tissue remains in the uterine cavity, preventing incomplete abortion, prolonged vaginal bleeding, or potential infertility.
