To confirm that the surge you detected was a final surge, continue taking Oaks until they are negative or until you’ve confirmed ovulation by seeing a marked increase in your basal body temperature, the temperature taken at the same time first thing every morning. According “Taking Charge of Your Fertility,” there are a number of things that can delay ovulation even once your body has shown the signs.
Polycystic Ovarian Syndrome (PCs), a condition in which numerous cysts develop inside the ovaries, can cause you to have an LH surge and not ovulate. The cysts are caused by trapped egg follicles that don’t release and fill with fluid.
In a condition called, Humanized Unruptured Follicle Syndrome (LUIS), the egg reacts to the LH surge but is unable to pass through the ovarian wall. Many fertility drugs, including Closed, can invalidate tests designed to detect an LH surge.

If pregnancy doesn’t occur, the corpus luteum shrivels up, stopping the secretion of progesterone, and triggering the start of a menstrual period. Your LH surge is important because it initiates the beginning of ovulation and your fertile period.
For many women, it’s easy to detect their LH surge using ovulation predictor kits (Oaks). These kits are similar to pregnancy tests because they measure hormone levels in your urine.
Each kit is a little different in how they register a positive result, so make sure to check the instructions. A positive result indicates the presence of a high amount of LH, or your LH surge.
The amount of LH in your body will begin to decrease after ovulation, so you’ll only get a positive result during that crucial fertile period. So knowing how long your cycle is (from one period to the next) will help you figure out when to start testing.
This is to make sure that you catch the positive result, in case you have a shorter cycle that month. Women with the condition polycystic ovary syndrome (PCs) might not be able to use these tests.
Some women with PCs have persistently elevated levels of LH, which would lead to an OPK always displaying a positive result, regardless of where you are in your cycle. Women approaching menopause may also have persistently elevated LH levels.
If you start testing too late into your cycle, you may miss the LH surge and won’t get a positive result that month. If you have trouble using an OPK, you can ask your doctor to run some blood tests to help you pinpoint your ovulation.
Usually, a gynecologist or reproductive endocrinologist (infertility specialist) can help you interpret the blood testing results. If you’ve been using these kits and haven’t become pregnant after six months (if you’re over 35) to a year (if you’re under 35), make an appointment with your doctor.
Anonymous patient There are three things necessary to get pregnant: an egg from the female (the product of ovulation), sperm from the male (the product of ejaculation), and an open passage from the uterus to the tubes for the two to meet. If the patient has been trying for at least six months (preferably 12) and there is no pregnancy, or if there appears to be an obvious problem with one or more of the three factors mentioned above, then she should see a fertility specialist.
Dr. Michael Weber Answers represent the opinions of our medical experts. Just before ovulation, a dramatic hormonal change takes place called the LHS urge.
If you want to remove the guesswork, digital ovulation predictor kits are your best bet. For pregnancy tests, if there is a second line, no matter how dark, it is a positive result.
A positive ovulation test means that your body has a higher level of LH than usual. The surge triggers the ovary to release an egg aka ovulating.
This forewarning helps you increase your chance of getting pregnant the very first month you use them. It indicates that your LH surge is strong and lasts longer than average.
The elevate LH can make using ovulation tests unreliable. If you have PCs and regular periods, ovulation test should work as expected.
Talk to your doctor if you are taking any of these medications and want to get pregnant. They can guide you about when to use ovulation kits and get accurate results.
For maximum accuracy, follow the ovulation prediction kit's directions to the letter. If you have an irregular cycle, ovulation tests will likely cause you much frustration.
You’ll have to buy many kits to use over a longer time to catch a surge at some point. Be sure to read the results of the test within the time frame stated in the instructions.
Testing twice will ensure that you don't miss your surge if you have a shorter than average LH surge. Having sex now and in the next two or three days will ensure that sperm will be waiting for your egg at ovulation.
The Luteinizing Hormone needs to go behind a certain threshold for ovulation to actually occur. Women with long cycles may have several LH surges before ovulating.

If you do have an LH surge combined with a temperature rise (shown by charting the whole month), does this guarantee that you've ovulated? A positive OPK combined with dip in temperature followed by a rise (at least 2/10's of a degree) higher than all temps the previous six days and staying at or beyond this level for at least 3 consecutive days shows that ovulation has occurred.
A positive OPK combined with dip in temperature followed by a rise (at least 2/10's of a degree) higher than all temps the previous six days and staying at or beyond this level for at least 3 consecutive days shows that ovulation has occurred. Many women who are able to conceive may have months that no ovulation takes place.
Thank you ever so much for your reply Rachael At the moment I'm simply convinced I'm not actually releasing any eggs yet to conceive, I may consider temping because as you say the temp dip and rise is a proof indicator of ovulation occurring. When you first started thinking about having a baby, the phrase LH surge probably didn’t cross your mind.
But if you’re trying to get pregnant, you’ve probably developed a sudden new interest in monitoring the level of luteinizing hormone (LH) in your urine. LH is a hormone produced by your pituitary gland that triggers ovulation.
But once the egg in your ovaries reaches a certain stage of development, LH levels increase rapidly. Since levels of LH spike about 24 hours before ovulation, tracking your LHsurgecan help you determine when your chances for pregnancy are highest.
If you wait for your LH surge to start having sex, you could be missing out on some of the best days of your cycle to conceive. These tests read a positive result when the level of LH in your urine is above a certain threshold.
If you start taking LH tests several days before you expect to ovulate, the idea is that you will “catch” your surge with enough time to have sex during your peak level of fertility. A 2018 paper called into question the practice of using LH tests to predict peak fertility.
The paper argued that the duration of the LH surge varies substantially both within and between women. This means that a single positive LH test doesn’t tell you that you are going to ovulate in 24 hours.
If you’re one of these women, a positive ovulation test doesn’t necessarily mean that you are fertile at all. A study in the journal Fertility and Sterility looked at how long the LH surge lasts in normally ovulating women.
The image below represents what different LH patterns would look like on daily LH tests from cycle day 11 through cycle day 21 according to the results of the study: Estrogen levels begin to rise roughly 5 days before ovulation.
Rising estrogen levels cause your vaginal discharge (also known as cervical mucus) to increase and become more slippery. This means that you should notice increased fertile vaginal discharge around the time of the LH surge.
PCs: This (and other hormonal conditions) can cause elevated LH levels throughout the menstrual cycle Humanized unruptured follicle (LUF): even though hormone levels leading up to ovulation are normal, the follicle doesn’t rupture, so the egg is never released. In normal menstrual cycles, the ruptured follicle becomes a corpus luteum, which releases progesterone and stimulates the lining of the uterus to build up.
But it is known that long term use of anti-inflammatory drugs can prevent the follicle from bursting, sometimes leading to LUF. If you’re taking anti-inflammatory drugs for chronic conditions like autoimmune diseases, arthritis, or endometriosis you may want to talk to your doctor about possible impacts on your fertility.
