Ok, this is what I found on a website, hope this helps...Kinda long...

Assuming that you know the basics of how to get pregnant, many people don't know how to make the process efficient. You'll want to give yourself the best chance of getting pregnant. To do that, you need to think a little about ovulation — the releasing of an egg from your ovary —which happens once each cycle (usually once per month).

After leaving the ovary, the egg spends a couple of days gliding down the fallopian tube until it reaches the uterus (also known as the womb). Most often, pregnancy occurs when the egg is fertilized within 24 hours from its release from the ovary, during its passage through the tube, and the budding embryo then implants in the lining of the uterus. In order to get pregnant, your job (yours and the father-to-be's) is to get the sperm to meet up with the egg as soon as possible (ideally, within 12-24 hours) after ovulation.

So when does ovulation happen? Typically, about 14 days before you get your period — which, if your menstrual cycles are 28 days long, is 14 days after the first day of your previous period. If you have a 32-day cycle, you probably ovulate on about the 18th day of your cycle. (each cycle begins on the first day of a period.) to make sure that you get the sperm in the right place at the right time, have sex several times around the time of ovulation, starting five days before you expect to ovulate and continuing for two to three days afterward. How often? Once every two days is probably adequate, but there's no reason to resist having sex every day if your partner has a normal sperm count.

It was once thought that having sex daily would result in a lower sperm count and reduce fertility. However, later medical studies found that this is true only in men who have a lower-than-normal sperm count to start with.

The absolute prime time to have sex is 12 hours prior to ovulation. Then the sperm are in place as soon as the egg comes out. Sperm are thought to live inside a woman's body for 24 to 48 hours, although some have been known to fertilize eggs when they are as much as seven days old. No couple should count on getting pregnant on the first try. On average, you have a 15 to 25 percent chance each month. Studies have shown that roughly half of all couples trying to get pregnant conceive within four months. By six months, three-fourths of them make it; by a year, 85 percent do; and by two years, the success rate is up to 93 percent. If you have been trying unsuccessfully to conceive for a year or more, a fertility evaluation is warranted.

You can take a few steps to improve your chances of conceiving:

if you smoke cigarettes or marijuana, quit.

Avoid using k-y jelly or other commercial lubricants during sex, because they may contain spermicide. (you may want to switch to olive oil or vegetable oil.)

find out when you're ovulating. If you succeed in doing this, you can plan your sexual encounters at the most opportune time.

Some women find that they can pinpoint their time of ovulation more easily if they keep track of their temperature, which rises close to the time of ovulation. To do this, you take your temperature (orally) each morning before you get out of bed. It typically reaches its lowest point right before your pituitary gland releases luteinizing hormone (lh), which triggers ovulation. (two days after the so-called lh surge, your temperature rises significantly — about a half to one degree above baseline — and stays elevated until you get your period. If you get pregnant, it remains high.) you may want to invest in a special "basal body temperature" thermometer (sold in most drug stores) because it has larger gradations and is easier to read.

Remember that a rise in your basal body temperature indicates that ovulation has already occurred. It doesn't predict when you will ovulate, but it does confirm that you're ovulating, and gives you a rough idea when ovulation occurs in your cycle.

Reading the signals can sometimes be hard because not all women follow the same pattern. Some never see a distinct drop in temperature, and some never see a clear rise.

Another way to monitor the lh surge is to use a home ovulation predictor kit, which tests the amount of lh in urine. As opposed to basal body temperatures mentioned previously, the lh surge is useful in predicting when ovulation will occur during any given cycle. A positive test for any cycle tells you that you're ovulating and when. In general, these kits are very accurate and effective. The main drawback is the expense. At $20 to $30 per kit, they're more expensive than taking your temperature.

In most cases, though, women are well advised to just relax and enjoy the process of trying to conceive. Don't get too anxious if it doesn't happen right off the bat. Here's one piece of advice we often give our patients: think about stopping birth control a few months before you actually plan on getting pregnant. This way, you have some carefree months of enjoying great sex without worrying each month if you are pregnant. And if you do conceive ahead of schedule, enjoy the nice surprise

Well look I now have my period and some people say that you have more chances for pregnacy when you have your period my period started the 18 of august it ends the 22 I want to know if thats true or when will be the days for more chances

No that's not true!

Yes, it is possible for a woman to get pregnant during her menstrual period. Though the chances of pregnancy are usually lower at the onset of a woman's period, there is no predictable time during the month when the risk of pregnancy is absent.

Here is a brief overview of how it could happen.


During each menstrual cycle, a woman's ovaries release an egg, or ovum. This process is called ovulation. This typically takes place an average of about 14 days before the start of a woman's monthly period, but the timing varies from month to month even in the same woman (and sometimes does not occur at all). After ovulation the egg moves toward the uterus through the fallopian tubes, where fertilization may take place. An unfertilized egg may live for about 24 hours. If it isn't fertilized, the egg will be shed during the next menstrual period, along with the lining of the uterus.


A woman is most likely to become pregnant if sexual intercourse occurs just before or just after ovulation. Sperm can survive for several days -- typically two or three -- inside a woman's body. Under ideal circumstances, however, they may remain viable for up to five days. So if sperm are deposited early -- such as during a woman's period -- they can hang around a few days, waiting until conditions are right for conception.


In addition to the survival skills of sperm, a recent study in the british medical journal highlights another reason why couples sometimes conceive during the woman's period. Research results indicate that the "fertile window," or time during the month when pregnancy can occur, is highly unpredictable for most women.


During the three-month study, researchers collected data about the hormone and ovulation patterns of 221 healthy women who were trying to get pregnant. They found that, overall, an estimated 2% of women were in their fertile window by the fourth day of their cycle, and 17% by the seventh day. (day one of the menstrual cycle is the day a woman starts her period.) on every day between days 6 and 21, there was at least a 10% probability, on average, that a woman could become pregnant. In addition, women who reported regular periods had up to a 6% probability of being fertile on the day that menstruation was expected to start. Ovulation was even harder to predict in women with irregular periods, according to the study. The researchers concluded that timing intercourse to avoid (or achieve) pregnancy is quite difficult and cannot be done with precision.
