The usual range for LH levels is 1.9-13.6 IU/L, but when a woman is fertile, that number can reach as high as 118 IU/L. The sensitivity level should be written on the test or in the description of the product online. Mumsnet has been helping parents make their lives easier since 2000 and, in those years, we’ve seen, tried and reviewed thousands of products. If your cycle is normally 28 days, the cycle chart above indicates you should begin testing on Day 11. The calendar below shows you how to work out when day 11 is. An ovulation test could indicate a false positive if your LH levels surge without ovulation occurring. Polycystic Ovarian Syndrome (PCOS) can cause women to have a high baseline of LH so there may not be sufficient change in levels to monitor a surge. What's the best ovulation test? First, you must determine the length of your menstrual cycle. This is the number of days from the first day of your menstrual bleeding to the day before your next bleeding begins again, count the first day of bleeding as day 1. Calculate what the usual length of your menstrual cycle has been the last few months. Once you have worked out the length of your cycle refer to the chart to determine on which day of your menstrual cycle you should begin testing.

Sex hormones were first measured in saliva by radioimmunoassay in 1978. Early publications focused on the correlation of salivary steroids to ovarian function, 19, 20, 51, 52, 53, 54 but exact ovulation time was neither determined nor even estimated, partly because reliable methodology was not yet available. Based on the theory that increased circulating estrogens stimulate the breakdown of glycogen, Alagendran et al. reported that levels of sialic acid and glycosaminoglycans (CAG) increased during the ovulatory period. 55 A change in urinary CAG level during the ovulatory phase was also demonstrated, as the ratio of urinary trypsin inhibitor/chondroitin sulphate peaked at menstrual cycle day 12. 56 I would recommend it if you want to learn about your cycles. It's really easy to use."(Advice from Mumsnet user Mseddy) Our verdict Some ovulation tests also measure an oestrogen metabolite, estrone-3-glucuronide (E3G). E3G levels rise over the 5 days before ovulation. Here, we feature some of the best ovulation tests as well as information about how to choose the right one for you. There are many ways to interpret BBT. In one approach, the “coverline” method, a horizontal coverline (which means a threshold temperature) is drawn on a BBT chart. When temperature above this coverline is recorded, ovulation is suggested. The coverline can be determined by adding 0.15°F to the highest temperature recorded during the first 10 days of a cycle, or by using previously recorded temperatures. Using the “three over six” rule, 34 three temperatures are required to be 0.2°F above the highest point of the previous six temperatures with at least one of the higher temperatures being 0.4°F above the lower ones.From digital to strips to apps, ovulation tests come with many different result images, but some of them can be hard to read. Digital tests may have a smiley face while strips will show you lines. More modern and tech-forward options allow you to scan your results through an app for ultra-clear results. Depending on your comfort level, you'll want to choose a test you feel confident reading. Most women with regular cycles will detect their L.H. Surge in 5 days or under and so 5 tests are sufficient, however, if you have irregular cycles you may need to test for longer and may require additional ovulation tests to detect your L.H. Surge Positive for L.H. surge– If two colour bands are visible and the test band is of equal or greater colour intensity (darker) than the control band, this is a positive result and a good indication that the L.H. surge is occurring. You should ovulate within the next 24-36 hours. Sexual intercourse is advised at anytime after the first positive test. The Maybe Baby is a mini microscope with a 52x power magnification lens that allows you to look at your dried saliva each day and monitor the crystallised patterns that are formed by increased salt levels – indicating that you’re due to ovulate. These methods include using an ovulation test, working out the length of your cycle so that you pinpoint your most fertile days (which tend to be 10 to 16 days before your period is due) and being aware of changes to your cervical mucus and basal body temperature (BBT). When should you start using ovulation tests?

Ovulation is a short window of time when a surge of certain hormones triggers the release of an egg from the ovaries.An ovulation test can be a really useful way of working out the best time to try for a baby. We've rounded up the best ovulation tests according to Mumsnet users. If you like the latest and greatest technology for every aspect of your life, this Clearblue monitor may be the right choice. It helps you detect not only your LH levels, like most ovulation tests, but your estrogen as well and gives you a rating each day that evaluates your fertility—low, high, or peak. Trying to get pregnant? Of course, there’s an app for that. This kit from Easy@Home works much like other ovulation predictor kits in that you dip the test strips in urine and wait to see if your LH level is surging, meaning your chances of getting pregnant soon are at their peak. It comes with 50 ovulation tests and 20 pregnancy tests as well. It takes three minutes for results – in the form of a smiley face to indicate that you're at your most fertile – to appear.
