Question
A woman suspects the paternity of her child. She started her menstrual cycle on November 24, 2018, which lasted for about 4 to 5 days before ending. On December 2nd, she had sexual intercourse with her ex-boyfriend, and then on December 3rd, 6th, 8th, 11th, and 14th, she had sexual relations with her current boyfriend. On January 9, 2019, an ultrasound examination was conducted, showing a fetal bud size of 0.3x0.2cm with visible fetal heartbeat. She wants to know who the child’s father is and how to calculate the delivery date.
Answer
Based on the information provided by the woman, if her menstrual cycle is regular, ovulation usually occurs on the 14th day after the start of her period, which would be December 8th. This day coincides with her sexual encounter with her current boyfriend, making the likelihood of pregnancy relatively high. Therefore, the estimated delivery date may fall within this timeframe. However, this is just an estimate and not entirely accurate. Please note this. The above is a suggestion for confirming the child’s paternity and calculating the delivery date in cases of suspected child paternity. I hope it helps and wish you health.
