Patient's question:
NoDoctor's answer:
Around 40 days of pregnancy (note: this is calculated from the day of fertilization, not from the last menstrual period), if the embryo develops normally, you can see the fetal bud and fetal heartbeat. It's also possible that due to slow development, you may not see the fetal heartbeat but can see the fetal tooth, but this is not considered a disease. If the fetus does not appear with a fetal bud or only has a fetal bud without a fetal heartbeat by two months, it can be confirmed as a miscarriage.
