Over to the wife!
So, we've been trying to conceive for longer than I care to remember and I have used just about every Ovulation Predictor Kit (OPK) out there-Tesco's and Sainsbury's cheapies, Boots (slightly more expensive) but never these. I was a bit wary of the smiley face business having been used to squinting at the tests to see if the line was darker than yesterday's etc as I didn't quite trust it would smile at me on the right day. The way the cheapies work, the test with the darkest line is your LH surge so you will ovulate approximately 24-36 hours afterwards and some of them recommend testing twice a day for complete accuracy. Once ovulation has occurred, eggs are viable for about 12 hours so there is a relatively small window. You also have to make sure you have allowed your partner's...ahem...stocks to replenish so that he has a minimum 48-72 hour break between attempts, especially if there are problems with his semen analysis.
The difference with these is that you get 2 days of high fertility, then peak fertility so plenty of time to plan! In practice, I have gotten maybe a day of high fertility and then peak fertility and have heard of plenty of other women who didn't get high fertility at all, and just had peaks.
What makes this test different from others is the following:
1. you use first morning urine (or as they say, first urine after your longest sleep). For most other OPKs this is a no-no as first morning urine is more concentrated and there is therefore a higher likelihood of a false positive LH surge.
2. It claims to test both LH and oestrogen (although they use the American spelling "estrogen"), claiming this makes it more accurate. I guess the oestrogen testing gives you an idea about when the LH rise is going to happen before it happens but plenty of OPKs work just as well without this. I guess when oestrogen is peaking and LH is going up is when you get the flashing smiley face.
3. It also clearly says to only test daily, whereas the cheapies tend to say that you may need to test more than once a day so as not to miss your surge.
In terms of price, it is competitively priced, especially for a kit with a holder. It hasn't miraculously made me pregnant yet, but then, there is a lot of other stuff going on that is likely the problem. It is very reassuring to know that I am ovulating and I guess that's how these tests help.
Why only 4 stars? Well, I don't like the unsubstantiated success claims! They need to reference any peer-reviewed research they have carried out on this product on the package insert. This is a bug bear of mine as there are many products that claim success at getting people pregnant but when you look at any research done, it is flimsy to say the least!
