One Step Ovulation/Fertility Test Strips
Advantages: cheap, easy to use, buy in bulk
Disadvantages: not very sensitive, can be inaccurate
I've been trying for a baby for many years now. There was a short interlude of 6 months where I was pregnant, but that didn't end how I'd hoped, so here I am again still trying for that ever elusive baby.
Why do you need Ovulation Tests?
The honest answer is that most people don't. Most people will either get pregnant quickly when they start trying or get pregnant accidentally when they weren't trying. Unfortunately some women aren't quite so lucky and have to go down the timed intercourse, monitored fertility route.
Many doctors will tell you that you ovulate around day 14 of your cycle. In reality most women ovulate about 14 days before their next period, not 14 days after their last period. This distinction between these two points can make a big difference. There are a few ways to monitor ovulation, and ovulation tests like these one step tests, test for the hormone LH in the urine. An LH surge happens about 12-36 hours before ovulation, so if you keep testing then you will notice a positive test and know when to have intercourse, so as not to miss the tiny 2 day window of of opportunity.
What does a positive look like?
Unlike pregnancy tests where a positive is any line at all, no matter how faint. On these One Step ovulation test, and most ovulation tests, a positive is where the test line is as dark or darker than the control line.
The tests have a thick green handle with an absorbent tip with a max line, they come individually wrapped in plastic wrappers with a little packet to prevent moisture.
Ease of Use
Simply rip open the packet (taking care not to rip your test) throw away the little packet inside and then dip your test into fresh urine. Urinating directly on these does not work and will cause an erroneous result. However, if you have no container to urinate in, I have had success urinating into the packet itself and dipping the test in there.
Dip for at least 10 seconds, but do not go over the max line. Then lay the test strip flat on a non-absorbent surface and wait for no more than 10 minutes for a result.
Reading the Result
Although in theory, the test line has to be as dark or darker than control, I find these tests are not very sensitive. I have used these tests every cycle for about 4 years (minus 6 months) and have only got a "true" positive on a handful of occasions - usually while taking clomid. Perhaps the sensitivity isn't great for these tests, different brands of tests will measure different concentrations of LH in your urine. Too sensitive and you will get a false positive before your surge, since most women have some LH in their urine every day. Not sensitive enough and some women won't get a positive at all.
These One step tests aren't that sensitive, at least for me. But I am still happy to use them as I know what a "positive" looks like for me. So although the line wont be as dark as control, I can tell that for me, it's my surge. I've tried other tests, like wondfo, and found them to be far too sensitive, resulting in days and days of positive results. These are much better.
Backing them up
If it's important for you to make sure you don't miss your positive - perhaps you are taking time sensitive fertility meds, or IUI, then it can be helpful to back them up with a digital ovulation test. My favourite is a clearblue digital, which shows a smiley face if you are ovulating or a blank face if you aren't. Usually a negative, but dark line on one step, is positive on my digital. But the digitals are expensive, and these are cheap, and since you need to test often it's best to only use the digital as a back up.
I buy these tests on ebay, and they usually cost between 7 and 10p each.
I have been using these tests for a long time and mostly I'm happy enough with them. They are cheap, they work well enough and I know my own body well enough to interpret these correctly. But if you do need certainty then a digital would be better
Summary: Overall, a good cheap way to monitor ovulation and hopefully get pregnant
