Patient's question:
I had my last menstrual period on March 17th, had intercourse on April 3rd, and again on April 7th. At 42 days, an ultrasound still couldn't detect a gestational sac, and at 69 days, the doctor calculated the baby was 8 days smaller. On which day did I conceive?Doctor's answer:
Generally, after 40 days of pregnancy, an ultrasound examination can reveal the gestational sac. Based on your ultrasound results, it is more likely that you conceived on April 3rd. However, the interval between the two sexual encounters on April 3rd and April 7th is too short, so it cannot be absolutely certain that you conceived on April 3rd. In fact, there is no need to worry about which day you conceived, as long as all aspects are checked and found to be normal, there is no need to be anxious.
