Thus, your fertile window ends 24 hours after ovulation. Some people advise using the basal body temperature BBT method over tracking your LH surge for pinpointing ovulation. However, BBT does not rise until 12 to 24 hours after ovulation , so you may miss your fertile window if you are using the BBT method alone to track ovulation. As cycle length and ovulation date could vary, starting early may reduce the risk of missing fertile days. However, testing more frequently is also more expensive due to the materials needed.
This sophisticated technology helps you to avoid missed fertile days while not wasting any tests at the same time. Mira empowers you to measure, monitor, and track hormone concentration levels in your body — specifically the fertility hormones LH and E3G.
To do this, you need to have the Mira Analyzer, several Mira Fertility testing wands, and the Mira app downloaded onto your phone or tablet.
Simply collect a urine sample in one of the provided cups, dip your test wand into the sample and leave it there for seconds, and then insert the test wand directly into the Mira analyzer.
This information will then be recorded and synced with the Mira app, allowing you to track your LH levels over the duration of your cycle. For most women, this surge in LH is a sign that ovulation should occur within the next hours. Together with your partner, you can use this information to plan intercourse on the days that you are the most fertile. For the majority of women, testing every 2 days after your period and every day close to ovulation should be sufficient for accurately predicting your LH surge.
Testing daily may also be advantageous for beginners wanting to know more about their fertility cycle and those struggling with hormonal conditions such as PCOS.

How long after an LH surge do you ovulate and how long does it last? Sylvia Kang. Fact Checked. Reviewed by Dr Roohi Jeelani. What is LH and what is an LH surge? About Dr Roohi Jeelani. Some women continue to test positive for three days after a positive ovulation test. The length of the LH surge is highly variable from woman to woman.
And the actual length of the LH surge does not determine your fertile window. 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:.
As you can see from this chart, some LH surges are long, and others are short. In the typical cycle, LH starts out low, then rapidly rises and peaks a day or two before ovulation, then falls back down right after ovulation. But just as not every woman has a textbook day cycle, not every woman has exactly the same LH curve. The LH surge itself does not have any physical symptoms.
But there are signs and symptoms of ovulation that you can track in order to determine when you ovulate. Most signs of ovulation are driven by the hormone estrogen. 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 is one of the best indicators that ovulation is approaching. Once estrogen reaches a certain threshold, this triggers the release of LH. This means that you should notice increased fertile vaginal discharge around the time of the LH surge.
But the discharge is a symptom of increased estrogen levels, not LH. Not necessarily. Think of the LH surge as a sign that your body is preparing for ovulation.
Ovulation usually will follow the LH surge, but having an LH surge is not a guarantee that ovulation will occur.
To confirm that ovulation occurred, you would need to observe an increase in basal body temperature , or have your progesterone levels checked by your doctor. It can also occasionally happen to women with otherwise normal cycles. In normal menstrual cycles, the ruptured follicle becomes a corpus luteum, which releases progesterone and stimulates the lining of the uterus to build up.
