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 showed no gestational sac, and at 69 days, the doctor calculated the baby to be 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, there is a high possibility 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, you don't need to worry about which day you conceived, as long as everything is normal after a thorough check-up, there is no need to be anxious.
