Everyones body is different, so their periods are different too whats normal varies from person to person, and can change over your lifetime. Some birth control methods or health conditions may also affect your period.

What Controls The Menstrual Cycle

Your hormones control your menstrual cycle. During each cycle, your brain’s hypothalamus and pituitary gland send hormone signals back and forth with your ovaries. These signals get the ovaries and uterus ready for a pregnancy.

The hormones estrogen and progesterone play the biggest roles in how the uterus changes during each cycle.

• Estrogen builds up the lining of the uterus.
• Progesterone increases after an ovary releases an egg at the middle of the cycle. This helps the estrogen keep the lining thick and ready for a fertilized egg.
• A drop in progesterone causes the lining to break down. This is when your period starts.

A change in hormone levels can affect your cycle or fertility. For example, teens tend to have low or changing progesterone levels. This is also true for women close to menopause. That is why teens and women in their 40s may have heavy menstrual bleeding and cycles that change in length.

Other things can change your cycle. They include birth control pills, low body fat, losing a lot of weight, or being overweight. Stress or very hard exercise also can change your cycle. Pregnancy is the most common cause of a missed period.

Understanding Your Next Menstrual Cycle And Fertilization

If you are trying to get pregnant you need to understand how the menstrual cycle works. The process starts when the thick lining of your womb starts to break up due to the decrease in estrogen and progesterone levels.

Without a sufficient amount of these hormones, your body will shed the lining and it will start to prepare for your next menstrual cycle.

However, if a sperm does make contact with and fertilizes the egg, it will close all pores to prevent more sperms from getting in there. The fertilized egg will stay in the fallopian tube for 3-4 days and then move to the uterus and attach to its wall, staying there for the long haul of pregnancy.

Your body will produce human Chorionic Gonadotrophin or pregnancy hormone right away .

The body will continue to produce the required estrogen and progesterone hormones so that the womb lining will not be shed and the placenta can grow mature enough that it can support the pregnancy.

Can You Ovulate More Than Once During A Cycle

A woman should not ovulate more than once during each cycle. This is due to a careful balance of hormones and their levels it takes just the right timing and release of hormones to bring on the release of a mature egg. Therefore, she cannot get pregnant more than once during a cycle. Remember, if you are not using a tracking method such as OPKs, basal body temperature, or cervical mucus, there is no guaranteed way to pin down the day you are ovulating. Many period tracking apps will give you your day of ovulation, but this is only an estimation of when it might happen. Thus, two days after the predicted ovulation day may not be a safe day to have sex to avoid pregnancy, since its possible that you have not actually ovulated yet.

Multiple ovulation is another phenomenon that can occur and is when two or more eggs are released in a single cycle. The eggs are released during one 24 hour period and are responsible for the birth of fraternal twins. It is believed that this may occur in as many as 5-10% of all cycles but does not result in that many twins due to a type of miscarriage referred to as the vanishing twin phenomenon.
