Pregnancy during ovulation is extremely rare, but it still occurs. If a woman undergoes in vitro fertilization during her ovulation period and the embryo develops well but fails to implant in the uterus, it may die naturally after a few days. This condition is called embryonic agenesis or abortion.

If a woman has IVF during her ovulation period and the embryo develops well, the woman should talk to her doctor as soon as possible to see if there is anything they can do to save the embryo. Women can also talk to their doctor to find out if they have any underlying health problems and if they need any treatment.

Overall, IVF is not a safe sex option. Women should use safety measures when having sex to avoid abortion and other complications.
