Undergoing IVF, after receiving so many fertility injections, why hasn't it worked?

Patient's question:

No

Doctor's answer:

Generally, the ovulation period is around the 14th day before the next menstrual period, and the three to four days before and after this period are also likely to be the time of ovulation, which is considered a risky period. The probability of pregnancy during this time is higher if sexual intercourse occurs. The rest of the time is relatively safe.
