Question

Will the child born to my girlfriend on the 15th be mine?

Answer

The size of the child is not calculated based on the time of sexual intercourse, but rather on the last menstrual period. You can diagnose the size of the child by calculating it based on her last menstrual period. According to the detailed results of your first ultrasound, the gestational age is approximately 35 days, which means you likely conceived on August 24th. If you’re saying you had intercourse on the 15th, then this result may not be accurate.
