Your doctor will count the start of your pregnancy from the first day of your last menstrual period. That's about 2 weeks ahead of when conception happens. Here's a primer on conception : Ovulation. Each month inside your ovaries, a group of eggs starts to grow in small, fluid-filled sacs called follicles. Eventually, one of the eggs erupts from the follicle (ovulation). It usually happens about 2 weeks before your next period. The so-called LH surge causes the release of the mature egg from the ovary-this is ovulation. Ovulation normally occurs 24 to 36 hours after the LH surge, which is why the LH surge is a good predictor for peak fertility. The egg can only be fertilised for up to 24 hours after ovulation. If it isn’t fertilised the lining of the womb is shed (the egg is lost with it) and your period begins. This marks the start of the next menstrual cycle. While an egg only survives for up to 24 hours, sperm can remain active for up to five days.  Ovulation can be calculated by starting with the first day of the last menstrual period (LMP) or by calculating 12-16 days from the next expected period. Most women ovulate anywhere between Day 11 – Day 21 of their cycle, counting from the first day of the LMP. The second half of the cycle is called the luteal phase and is from the day of ovulation until the next period begins. The luteal phase has a more precise timeline and usually is only 12-16 days from the day of ovulation. This ultimately means that the day of ovulation will determine how long your cycle is Pregnancy is technically only possible during the five days before ovulation through to the day of ovulation. These six days are the ‘fertile window’ in a woman’s cycle, and reflect the lifespan of sperm (5 days) and the lifespan of the ovum (24 hours). 1 Day one is the first day of the menstrual period and the last day is the day before the next period begins. 2  Ovulation happens about two weeks before the next expected period. 3  So if your average menstrual cycle is 28 days, you ovulate around day 14. Tracking Ovulation: A woman’s monthly cycle is measured from the first day of her menstrual period until the first day of her next period. On average, a woman’s cycle normally is between 28-32 days, but some women may have much shorter or much longer cycles. The second half of the cycle is called the luteal phase and is from the day of ovulation until the next period begins. The luteal phase has a more precise timeline and usually is only 12-16 days from the day of ovulation. This ultimately means that the day of ovulation will determine how long your cycle i They also release one egg each month for possible fertilization. A number of different conditions, from cysts to tumors, can cause ovarian pain. The ovaries are located in the lower abdomen. That means if you have ovarian pain, you'll most likely feel it in your lower abdomen -- below your belly button -- and pelvis. It's important to have any pelvic pain checked out by your regular doctor or obstetrician /gynecologist. Several different conditions can cause it. Cysts are fluid-filled sacs that can form in the ovaries. They are very common in women, especially during the childbearing years. Often they form during the process of ovulation. It can happen when the egg is not released or when the sac -- follicle -- holding the egg doesn't dissolve after the egg is released. Ovulation is the part of the menstrual cycle where the ovary releases an egg to be fertilized during conception, or sloughed off during a woman's period. Ovulation is a part of the menstrual cycle when the ovary releases a ripe egg, or ovum. Inside the ovary are hundreds of thousands of follicles. Each follicle is a hollow ball of cells with an immature egg in the center. The typical 28-day menstrual cycle begins on the first day of menstrual bleeding If fertilization does not occur the egg dissolves after 24 hours. At this time your hormone levels will decrease and your uterine lining will begin to shed about 12-16 days from ovulation. This is menstruation (menstrual period) and brings us back to day 1 of your cycle. The journey then begins all over again. The second half of the cycle is called the luteal phase and is from the day of ovulation until the next period begins. The luteal phase has a more precise timeline and usually is only 12-16 days from the day of ovulation. This ultimately means that the day of ovulation will determine how long your cycle is
