Generally, it is 28 days, but it can also be longer. On a 28 day cycle right around day 14 ovulation happens and the ovum is viable for a 5-6 days in the uterus, so if you have sex from day 11-20 it is possible you can get pregnant. Sperm can live in the uterus 5-6 days and this has to be taken into account when counting days of a cycle.
