Patient's question:
How much difference can there be between the pregnancy days shown on ultrasound and the date of intercourse? Can it exceed 20 days? Is there an approximate range?Doctor's answer:
Analyzing the situation you described, if the number of days of pregnancy is greater than the number of days of your period, this may be related to early ovulation. Alternatively, it could be that your last menstrual period was very light and should not be considered a true period—you might already be pregnant and experiencing vaginal bleeding. This situation is also quite normal. During early pregnancy, it is recommended to take folic acid orally to prevent neural tube defects in the fetus. Avoid sexual intercourse for the first three months to prevent miscarriage.
