The methods for preventing pregnancy are fairly direct (although not always foolproof). When it comes to conceiving, however, you may find that there's a lot more planning -- and even guessing -- involved. How can something so natural take so much work?
Fortunately, it may be easier than you think to find those magical days of ovulation when you're most fertile. There are a number of options, and most can be done on your own:
Bodily observations: Ovulation isn't nearly as conspicuous as menstruation, but if you pay attention to your body, you can sometimes tell you're ovulating. Signs might include light spotting, slight abdominal pain on one side and increased sex drive [source: American Pregnancy].
Calculating your cycle: Ovulation generally occurs in the middle of your cycle, and can be anywhere from day 11 to day 21 [source: American Pregnancy]. To pinpoint this phase, count from the first day of your last menstrual period. There are many online ovulation calculators you can use to help with this.
Charting your basal body temperature: When your body releases an egg, it also releases progesterone, a hormone that thickens your uterine lining and also slightly increases your body temperature [source: WebMD]. You can find basal thermometers at most drugstores, and use them to see if you can detect a rise in temperature during certain times of the month.
Tracking the luteinizing hormone (LH): This hormone is responsible for releasing an egg during ovulation. Ovulation kits that check for LH levels in your urine provide a fairly accurate means for determining ovulation [source WebMD].
Now that you know how to find your most fertile days, your next step is to take advantage of them. And don't pressure yourself to find the exact day of ovulation; viable sperm can live in the reproductive tract for up to three days [source: American Baby].
