## Description

From the brand

Review: Great - High recommended, cheap but works like the expensive one.
Review: Cheap, effective, OPKs a must have for TTC! - We'll be trying for another baby really soon so I've stocked up on these. Compared with the cost of ovulation predictor kits that can be found in supermarkets, One Step OPKs are such great value for money. I use Glow app to track my fertility. I start using these sticks on the run up to my predicted ovulation. Unlike a pregnancy test, the best time to take an OPK test is in the afternoon. Just hold the stick in urine for over 10 seconds for a quick result. Don't forget, OPKs don't work like a pregnancy test, where even a faint line is a positive. If the line is faint, it's most definitely a negative. I made this mistake at first. I see a faint line several days in the month. This is caused by a LH (luteinising hormone) surge that can happen in your cycle around the time of ovulation.

## Features

- PREDICT OVULATION WITH PRECISION: Our One Step Ovulation Test Strip is a fast and accurate way to find out when you're about to ovulate, which is the best time to conceive. It detects hLH surges in your urine, indicating that ovulation will likely happen within the next 24-36 hours
- EASY-TO-USE, NO HASSLE: This test strip is user-friendly. Simply dip it into your urine sample. No complicated steps. It's 2.5mm wide, making it convenient for you to handle at home
- SEE THE RESULTS CLEARLY: When hLH is present in your urine, a unique red line appears on the test strip. The line's darkness varies based on the concentration of hLH. This gives you a clear visual signal that ovulation is on the way
- CONFIRMATION FOR PEACE OF MIND: Our test strip includes a control line with labelled antibodies. When you see this line, you can be sure you've used the test strip correctly and that it's working as it should. It's like a built-in quality check
- BUILT-IN CONTROL LINE: We use a method called "immunochromatography" to make this test reliable. It's a proven way to ensure that you get accurate results when you're trying to predict your ovulation and plan for your family's future

## Questions & Answers

**Q: What time of day do you take a test? Do you test multiple times a day?**
A: Near ovulation I tested 3 times per day and tested around 10am, 2pm and 10pm. Pregnant 1st month ttc.

**Q: How many do you get?**
A: One test trip in each individual packet

**Q: What does it mean if the is the control line is faint each time but no test line? In have tested 4 times over the last 8 days.**
A: Are you using first morning urine? Could be diluted if it’s later in the day. Make sure you pee in the pot first then dip in.

**Q: Do they have a use by date?**
A: Yes, I bought mine last year and that are still in date until 2018.  I would highly recommend them, I bought the clear blue ones too but these seemed to be more accurate.  And I now have a two month old baby boy.  Good luck to you.

### ⭐⭐⭐⭐ Very effective...once you realise what a positive looks like!
*by S***E on 26 January 2017*

After coming off the pill a few months ago to try for a baby, I've had quite long cycles, so decided to use ovulation tests and charting to try and pinpoint ovulation. They arrived quickly and in a plain envelope that went through the letter box. After trying the one step tests for several days, I thought they weren't working and was getting fed up...It always seemed to be nearly as dark as the control line but not quite and I spent ages analysing whether it was a positive or not. Then one day the test line came up almost straight away, just before the control line and went dark very quickly- ah now that's what a positive looks like! I also chart my temperature as well, to confirm that ovulation did happen (some people can get a positive without ovulating, especially with PCOS). I've tried the clear blue digital dual hormone test but that was too expensive to use if you have a long or irregular cycle and seem wasteful with all the plastic holders, I much prefer the one step cheapies as you can use them freely over may days without worrying about cost so much. It is best not to test first thing in the morning as the LH surge usually happens in the morning and therefore is not detected in the urine until some hours later so mid afternoon -early evening is usually recommended. The only slight downside is that they are 'pee in a pot' test and not a 'pee on a stick' test, which is not always the most convenient. I'm not pregnant yet but will continue to use these in my ttc efforts as they are cheap and effective.
