Ovulation takes place about 2 weeks (usually 12-16 days) *before* the next period. In any individual woman, it is even more limited; she may ovulate 12-13 days (or even 12-14 days) before, but she can't ovulate 12 days before her period one cycle and 16 days another.
The reason for this is that ovulation *causes* the next period. When you ovulate, the follicle of the egg remains behind at the ovary and produced progesterone that protects the uterine lining long enough for an egg--if one gets fertilized--to get to the uterus and implant. The follicle has a fixed lifespan (unless you get pregnant), then it dies.
But a woman can be very irregular and ovulation can take place on different days counting from the *beginning* of a cycle. This can be for many reasons. An occasional long cycle, for example, is usually caused by stress *before ovulation* that delays the hormonal production that leads to ovulation. Or her hormones could just be more sensitive than most women's and have variable length cycles for this reason. Again, it would have to be something *before* ovulation that changes cycle length. Lastly, she may not be ovulating every cycle; in this case, the bleeding isn't even a period--it is withdrawal bleeding or breakthrough bleeding.
In some cases, it may *appear* that a woman has different lengths of time between ovulation and her next period. There are two possible reasons for this.
Either she didn't ovulate when she thought she did--her body may have *prepared* for ovulation (giving a positive on an ovulation predictor kit), then not ovulated. In this case, she may have actually prepared for it *again* a few days later or not ovulated at all, screwing up the timing.
Or, she may have ovulated, gotten pregnant, and then had an early miscarriage a few days later.

RE:
Can ovulation occur at anytime in the cycle and each month is different from the other? For example can a woma
n have her period on the 6th and ovulate on the 22nd and the next month have her period on the 10th and ovulate on the 29th? Is it always different and what does it depend upon?

Some women do have very irregular cycles. Ovulation usually occurs 14 days before the start of the next period, even with the irregular cylces. It is the time before ovulation the usually varies.

From what I understand, ovulation takes place normally 5-7days after mensturation stops. Thats the reason women on contrceptive pills, are advised to take their pills on the 3rd day after the menstruation ends. Normally ovulation wont occur 5-7days after your mensturation stops and also a week before your period comes again (the called this the 'safe period'), if your period cycle is regular, meaning your period always comes almost the same date every month. If your period is irregular, you can take the risk practising sex for 5 days after the last day of your period flow, but not the few days before your not so sure period coming date.Hope you catch what I mean.

Usually the woman ovulation periods starts 7 days after your last period and the cycle of your next period is usually 28 days. You should start counting your next period from the date you got the period. For example if the period date is 2 June then your next period is 28 days later , 29 June. There maybe certain factors that will contribute to how fast your next period will be, your lifestyles for instant. But ovulation usually stays on track.

Hon, You ovulate two weeks BEFORE your period. The reason you have a period it the uterus softens for the egg to implant. When it does not get impregnated, it will slough off and thus the bleeding and cramping and it will all begin the next time.. It is so very common NOT to do it on the same day each time there is no reason to worry.. Good luck and God bless. Hugs from Texas.. {:-)

A female only ovulates once a month. If a female ovulated more than once, which is unheard of, then she would have 2 periods in one month.

When does Ovulation take place?
Ovulation takes place, on average, about two weeks before your period, though it can vary from 10-16 days before the onset of menstruation depending on the length of your luteal phase. During an “average” 28 day cycle, ovulation is usually expected to take place between cycle days 13-15. Based on this guideline, many women are taught to expect ovulation around day 14 of their menstrual cycle. Many women, however, do not have average cycles and even those who usually do may see irregularities from time to time.
A typical menstrual cycle may be anywhere from 21 to 35 days according to the American Society for Reproductive Medicine. Some women even notice cycles that are shorter or longer than this. Ovulation, then, may occur much earlier or later than typical guidelines suggest. For example, ovulation may occur on cycle day 23 during a cycle that is 35 days long for a woman with a 12 day luteal phase while ovulation may occur on cycle day 10 for a woman with a 24 day cycle and a 14 day luteal phase length. This variation among women and from cycle to cycle means that there is really no simple “one-size-fits-all” mathematical formula to calculate your ovulation date. However, it is possible to learn how to identify your own ovulation date and fertile signs by examining your fertility signals.
Detecting Ovulation
Your ovulation date and your time of peak fertility can be detected by charting your fertility signs. This is because our bodies produce signals that can alert us that ovulation is approaching and tell us when ovulation has passed. Fertility signs that indicate that estrogen levels are high and ovulation is approaching (and fertility is high) include observing increasingly stretchy and “egg white” cervical fluid and observing a high, soft and open cervix. Commercial devices such as ovulation prediction kits (OPKs) and fertility monitors can also tell us that ovulation is approaching by measuring the presence of estrogen or luteinizing hormone (LH) in urine. Charting your basal body temperature (BBT) allows you to pinpoint the day of ovulation and tells you when ovulation has passed because progesterone raises the basal body temperature after ovulation.
Can Women Ovulate Multiple Times in a Single Menstrual Cycle?
by Shana R. May
Women ovulate more than once a month: Study (JULY 9, 2003): published by Dr Pierson in Fertility and Sterility.
What did they do?
In the study high-resolution ultrasound scans, which allowed them to see the follicles very clearly, were conducted daily on 68 women over a period of 6 weeks.
What was the previous train of thought on ovulating more than once in a month?
Standard medical science says a woman has a cycle running roughly 28 days in which an egg ripens, is released by the follicle, drops into the fallopian tube, and then is either fertilised or shed during menstruation.
What's it mean?
A Canadian study concludes that many women ovulate more than once per menstrual cycle.
10% of the women studied released two eggs in the same month.
A growth wave of 15 to 20 egg-carrying cells called follicles occurs before ovulation.
100% of the women in the study had at least two of these "waves".
30% of the women had three "waves".
The "waves" don't always lead to ovulation, however.
In the study, within 6 weeks, 50/68 women only ovulated once.
6/68 women ovulated twice.
7/68 women didn't ovulate at all.
Most of those "waves" came after they had ovulated, but some had the potential to ovulate immediately after their menstrual period.
In some cases, follicle development didn't reach the point where the egg would normally be mature enough to release.
The researchers don't know whether the pattern for each woman is constant, or whether it changes from month to month.
Implications:
May explain why the rhythm method of contraception is so unreliable.
Could lead to improved, targeted fertility treatments in the future.
May explain why the conception rate for non-identical twins is as high as 10%.
What prevents both eggs from becoming a pregnancy every month?
Other parts of a woman's reproductive system must also be at the right stage for a fertilized egg to implant in the uterus.
I hope you become pregnant real soon as i wish the best for you. If you feel as though something may be wrong with you conceiving go to the doctor.
I know i don't know where you are in the world but i know a doctor that can help you become pregnant

Good Luck!! (sorry so long)
