If your period is on the 11th, then ovulation is on the 14th day from the start of your period. During this period, your egg is waiting to be fertilized and travel through the fallopian tubes into the uterus. If you are trying to get pregnant, this is very important.

To sum up, pregnancy requires the coordination of many factors, including the menstrual cycle, safe periods, the days between safe periods, and the quality of sperm and eggs. If you're trying to get pregnant, it's recommended that you work with your doctor to make a plan and be prepared in every way.
