Can my boyfriend getting in half way cause pregnancy?

Patient's question:

No

Doctor's answer:

Hello, generally the 14th day before the next menstrual period is the ovulation period, and the three to four days before and after this period are all possible for ovulation. Choosing to have intercourse during the ovulation period, once every other day, for three consecutive times greatly increases the chances of pregnancy. You can do a blood HCG test 10 days after intercourse to detect early pregnancy earlier.
