Took clomid (clomiphene) 50 mg, 5 gonal injection, pregnyl injection. did sex in ovulation days . why i may not be pregnant?

Common: The in general the chance of not being pregnant is much higher than the chance of being pregnant. You may have a 10% chance of being pregnant and a 90% chance of not being pregnant. That is because the treatment does not affect fertilization, take into account egg quality, help the sperm, or deal with the tubes. So the vast majority of women will not get pregnant at any given treatment.
