If you have your period on September 25th, then you will be ovulating from September 25th to October 9th. If you are trying to get pregnant, it is very important to use safety measures plannedly during this time.

Women trying to get pregnant can better understand their menstrual cycles and ovulation by observing changes in their bodies. For example, basal body temperature can be measured in the middle of the menstrual cycle (about day 14 of the menstrual cycle) to determine whether the body is in a state of rising body temperature. You can also observe the moistness of the vaginal wall during the first 7 days and the last 8 days of the menstrual cycle to determine whether you are in the ovulation period.

If you're hoping to get pregnant, it's a good idea to talk to your doctor or nutritionist to learn how to better plan your diet and exercise, and how to improve your body's nutritional levels to improve your chances of conceiving.
