What is the probability that after getting a positive home ovulation test/lh surge that someone not ovulate?

What is the probability that after getting a positive home ovulation test/lh surge that someone not ovulate?

Good question: There is some variability in9 the accuracy of the available otc ovulation prediction kits. If it's working, then the ovulation should occur for the overwhelming majority (>95%) of patients who experience the lh surge. You can have your doctor order a day 21 Progesterone level, and that will confirm ovulation (or prove it didn't occur), to help you be sure. Read more

Miscarried at 4th week, Bleeding stopped on 5th day. When will I ovulate? Will it start with LH surge like it normally does in a cycle b4 my next period?

Miscarried at 4th week, Bleeding stopped on 5th day. When will I ovulate? Will it start with LH surge like it normally does in a cycle b4 my next period?

Yes: Everything goes back to normal the moment pregnancy is over. You will ovulate even before you have menses.So you could potentially become pregnant without a period. Read more

How soon after LH surge does estrogen levels drop and ovulation happen?

How soon after LH surge does estrogen levels drop and ovulation happen?

LH surge to ovulate: Ovulation happens approximately 36 hours after the LH surge. Serum estrogen levels reach a peak about 24 hours before this occurs and come down dramatically afterwards. Read more

How many days after a positive LH surge ovulation test can conception happen?

24-48 hours: The usual time of ovulation is 24-48 hours after the + surge is seen. The surge may show positive for 1-3 days. If you catch it on the upswing it could be 72 hours later. Read more

How long after LH surge will I be fertile? Does LH surge decreasing means ovulation is complete?

LH AND fertility: Clearblue offers a range of ovulation test and fertility products, all of which monitor luteinizing hormone (LH) in urine to identify the time of peak fertility. The Clearblue Fertility Monitor and Clearblue Advanced Digital Ovulation Test also measure another key hormone, estrogen (estrone-3-glucuronide) to identify the period of high fertility that occurs prior to the LH surge. Monitoring these two hormones helps women identify the fertile days of their cycle enabling them to time intercourse to the days when conception is most likely There are only a few days per cycle when a woman is fertile and can conceive. Evidence shows that this time of high fertility usually spans 6 days, starting approximately 5 days prior to ovulation and ending on the day of ovulation itself.1 The 6-day fertile period is affected by: The lifespan of the egg, which is up to 24 hours after ovulation The lifespan of sperm which is more variable. The median is 1.5 days, but sperm can survive up to 5 days in the sperm supportive mucus found in the fertile days of the cycle. Sperm survival is therefore dependent on the type and quantity of the mucus within the cervix, and the quality of the sperm itself. The two most fertile days of this 6-day window are known as peak fertility days. These peak fertile days are the day prior to ovulation and the day that ovulation takes place.2 Studies show that a surge in LH levels occurs 24-36 hours prior to ovulation, 2 and that this LH surge is an accurate and reliable marker of impending ovulation.3-7 The urinary LH surge pinpoints the two peak fertile days of a woman's cycle, with intercourse on these days being shown to be associated with the highest likelihood of conception.

Does the LH surge remain elevated through ovulation or does it go back to normal and then the egg drops?

Does the LH surge remain elevated through ovulation or does it go back to normal and then the egg drops?

LH peak: LH rises, peaks, and declines within a 24 hour period, with variations, though, among women. During this time period the egg bursts through the surface of the ovary and is swept up by the fimbria of the fallopian tube. Read more

Does an OPK shows a positive LH surge even during ovulation? If not, how much time before ovulation LH drops.

Does an OPK shows a positive LH surge even during ovulation? If not, how much time before ovulation LH drops.

Ovulation: The OPK should be positive just before ovulation. If it's still positive with your period, it could be that you're producing the hormone LH in high amounts, or the kit could be wrong. Read more

What happens to LH surge during ovulation? Would the LH detector still give a positive read if u are ovulating?  

Yes it could: An lh surge is triggered when estrogen production from a growing follicle reaches a certain level. Some lh surges go up and down in 1 day. Others can be positive for 3-4 days. Ovulation usually occurs 24-36 hours after the peak so it is possible that the lh surge could still be positive during or after ovulation. Ovulation is triggered by the lh surge but the lh surge is not changed by ovulation. Read more

Once you get a neg OPK for LH surge following a positive does that mean ovulation has finished. How long can you see positive OPK after ov?

Once you get a neg OPK for LH surge following a positive does that mean ovulation has finished. How long can you see positive OPK after ov?

OPK: An opk is a test that measures luteinizing hormone. Just prior to ovulation, women experience a short surge where the lh levels rise. The opk will help you pinpoint this surge and help you predict when you will ovulate. It rise the day before ovulation and does not stay high very long. Read more

28-30 day cycle. Took clearblue digital ovulation test (not advanced), & had LH surge detected on day 8 and 11. Why multiple days? & so early?

28-30 day cycle. Took clearblue digital ovulation test (not advanced), & had LH surge detected on day 8 and 11. Why multiple days? & so early?

Variable: Ovulation tests must be done daily at the sam time and with making sure that you have the same urine concentration. A more concentrated urine will give you false positive ovulation test. So, please repeat it again daily till Day 16 or till it is consistently positive. In a 28 to 30 day cycle, you are most likely to ovulate Day 14 to 16. Please start testing only from Day 12 of your cycle next time Read more

I have had a positive LH surge from ovulation tests for 5 days. Is this normal? If not, what could the reason be? Cycle are typically 50 days.

I have had a positive LH surge from ovulation tests for 5 days. Is this normal? If not, what could the reason be? Cycle are typically 50 days.

OPK: The accuracy of opk varies - sadly, the opk are more reliable the more regular your cycles are normal, meaning the women who need them most will get the least use out of them. 5 days of "lh surge" is not physiologic, so it's either a bad test or you have a very unusual ovulation. Read more

I have a CD27, I normally get a LH surge on cd11@11a;however, I took another ovulation test and it was positive today at 11:00a cd14 I'm confused?

Not to worry!: No woman's cycles are 100% identical every month & tthe hormones regulating cycles are VERY complex. A small variation in the rate of maturation of the ovarian follicle can lead to a variation in the timing of the LH surge which can last from 24 to 48 hours. What you observed is a perfectly normal, modest hormonal variation. It's not until menopause that the cyclic variation goes away. Read more

Is a 3 day LH surge normal. I get this every month and when I have done tests to check whether I have ovulated. The test come back I have ovulated?

Is a 3 day LH surge normal. I get this every month and when I have done tests to check whether I have ovulated. The test come back I have ovulated?

Test once: Once you have a positive ovulation test then you stop testing as the test will stay positive for a few days. There is no reason to continue to check it Read more

1st LH surge day 15, negative for LH day 16. Does that mean I'm ovulating on day 16? I typically get two days of LH but this time only one? Fertility?

1st LH surge day 15, negative for LH day 16. Does that mean I'm ovulating on day 16? I typically get two days of LH but this time only one? Fertility?

Day 16 or 17: The lh surge goes up and down over about 24 hours. When you get two days of positive lh tests you are probably catching lh rising the first day and going down on the next day. It can be 24 to 36 hours from detecting the lh surge to ovulating, so you could ovulate on day 16 or up to day 17. Hope this helps. As you are doing iui, ultrasound monitoring of your cycle can help with timing IUI as well. Read more

Using ovulation test strips to pinpoint my LH surge. Positive on 9/21 but my calendar says I ovulated on 9/19 I tested that day an got negative, help?

Using ovulation test strips to pinpoint my LH surge. Positive on 9/21 but my calendar says I ovulated on 9/19 I tested that day an got negative, help?

Mix n' match: Don't be surprised: you are mixing testing methods, none of which is (are) exact. If you checked cervical mucus you might get another answer, still. Generally the opk is the most accurate test you can do at home; more reliable than the calendar method, and ultrasound is more reliable than opk. Read more

Probably: The ovulation kit is only supposed to be positive for a day or two, so that sounds good. You may want to check out my book tick tock, which tells my own fertility story and teaches some fertility. Read more

I have a question about detection of ovulation with a opk? I started using the clear blue digital ovulation test 20pk day 6 of my december cycle to try and catch my LH surge. I tested twice everyday, once at 1p the other about 10p. The first time I detect

I: I agree with the rep that the 1st day that you detected a surge most likely represents your true lh surge. The cramps that you described are often experienced by women that ovulate but their timing is less specifically related to the exact time of ovulation. Implantation is usually not associated with discomfort. Cramping pain lasting more than 2 days is less likely to be related to ovulation but may be common when ovulation inducing drugs are used or patients have other underlying condition such as endometriosis. Keep in mind that there is only about a 20% chance of conception each cycle under optimal conditions. If you have proven past fertility and continue to ovulate you should have an excellent chance of conception within a few cycles. If you are not pregnant within 3 or 4 months or over 35, other testing should be considered. Read more
