Pregnancy tests work by detecting the presence of human chorionic gonadotropin (hCG) in your urine.
hCG and LH are both known scientifically as glycoproteins, which simply means that these hormones are made up of a protein with a sugar attached to it.
A positive result on an ovulation pregnancy test taken after you have missed a period could definitely indicate that you are pregnant.
But, while it might be tempting to use your extra ovulation test as a pregnancy test, most ovulation predictor kits (OPKs) are not as sensitive as an early detection pregnancy test, which means that you will run the risk of getting a false positive even if you are pregnant.
Your OPK will not be sensitive enough to detect the small amounts of hCG that are present in your urine in the first few days after conception.
If you suspect that you have conceived, the quickest, most accurate way to confirm pregnancy is to use an early detection pregnancy test.
But there is no evidence that using them will improve your chances of getting pregnant naturally.
Regular sex throughout your cycle is the best way to maximise your chances of conception.
However, you may prefer to schedule sex for your fertile period if...
There are a few ways to determine your fertile window. You could record your menstrual cycle, chart the monthly cycles of your basal body temperature, or study changes in your cervical mucus. Or you could try all three.
However, it can be tricky to pinpoint ovulation using these methods, especially if your menstrual cycles are irregular. This is where ovulation predictor kits (OPKs) can help.
An OPK is a quick, easy and accurate way to predict ovulation in advance. It allows you to pinpoint your fertile window from the very first month.
Kits are available online, and at most chemists and supermarkets. You can usually find them in the same section as pregnancy tests.
Coloured bands will appear on the test card or stick to indicate whether or not the luteinizing hormone (LH) surge is occurring.
Digital OPKs use symbols, such as a smiley face, to tell you when you are on your most fertile days.
Instructions may vary slightly depending on which kit you use, but in general you should try to collect your urine between 10am and 8pm. The optimum time is supposed to fall between 2pm and 2.30pm.
Try to collect your urine at about the same time every day, though this is not absolutely necessary.
Don't test your urine as soon as you wake up, because you may miss the first day of your LH surge.
Try to reduce the amount of liquids you drink for about two hours before you do the test. Too much liquid will dilute your urine, which could make it more difficult to detect the surge.
Read the results within 10 minutes for the best results. A positive result will not disappear, but some negative results may later display a faint second colour band.
So throw the test card away once you've read the result. Urine-based OPKs generally provide five to nine days' worth of tests.
Using a salivary ferning OPK is perhaps easier, as all you have to do is place some of your saliva on a slide by using your finger or licking it.
Do this first thing in the morning, before you've had anything to eat or drink. Make sure you don't put too much on and that it is free of any air bubbles.
You then wait for the saliva to dry and then use the microscope to see whether there is any ferning or not. Compare your slide with examples in the instructions to see whether you're in your fertile window.
With either type of OPK, it helps to work out when your fertile period is likely to start. It's usually the length of your usual cycle minus 17 days.
So, if you have a 28-day cycle, start testing on day 11 and carry on for six days.
Long gone are the days where you had to wait until your period was late before you could determine if you were pregnant or not.
These days, home pregnancy test is extremely sensitive and accurate. Some are even as sensitive as the urine test you would take during a doctor's visit.
Digital planning to help you become pregnant is the easiest way to test for fertility, ovulation, and a baby.
Whether you are hoping to get pregnant or you are in need of a test to tell you that you are not pregnant, going digital is the clear choice.
