Patient's question:
The ovulation period is from the 31st to the 9th. On the 9th, I had sex with someone else without ejaculation. On the 23rd, I had a thorough check and found I was four weeks pregnant. So, is the child my boyfriend's or someone else's? Before the 9th, I only had sex with my boyfriend.Doctor's answer:
According to the materials you purchased, the summary is as follows: You are unsure of your ovulation day, so it is recommended that you purchase the date of the first day of your menstruation in October, as well as your usual menstrual cycle (how many days it occurs, from the first day of bleeding to the first day of the next month). In summary, it is recommended that you first confirm the ovulation day to roughly calculate the day with the highest possibility of delivery.
