Ovulation Test FAQ

If used correctly, ovulation tests are excellent predictors of ovulation. However, in order to detect the LH surge with accuracy, directions must be followed exactly. The most common mistake made with OPKs is generalizing the methods of pregnancy testing to ovulation testing - which leads to errors in use and in the interpretation of results. To get the most out of ovulation testing, read our Ovulation Test FAQ.

Ovulation Test FAQ

Q: How do ovulation tests work?

ovulation test FAQ Ovulation tests detect luteinizing hormone (LH). Just prior to ovulation, women experience a brief surge in luteinizing hormone. Ovulation predictor kits help you pinpoint this surge and anticipate ovulation - your most fertile period in your cycle. Luteinizing hormone, in elevated amounts, is actually the hormone that causes you to ovulate (when the eggs bursts from the ovarian follicle), so that is why lh tests are so effective in anticipating your most fertile time.

Q: How do I interpret results? The same as pregnancy tests?

Ovulation tests function differently than hCG pregnancy tests. A positive result (indicating an LH Surge) is indicated by a test band that is of equal or greater intensity (equal or darker) than the control band. A negative result for the LH Surge is indicated when the test band is of lesser intensity (lighter) than the control band or cannot be seen. Click here to see diagrams of test results.

Q: What is the best time of day to take the ovulation test?

ovulation test FAQ Unlike pregnancy tests, morning (first morning urine) is not the best time to collect samples for ovulation tests, as LH is synthesized in your body early in the morning and will not appear in your urine until the afternoon. The ideal time to test is in the afternoon, around 2pm, though testing may safely take place from 10am to early evening.

Q: Should I take the test the same time every day?

ovulation test FAQ Yes, be sure to test at the same time each day. Also, reduce your liquid intake around 2 hours before testing as a diluted liquid sample can prevent or hinder LH detection.

Q: When should I beginning testing with the ovulation predictor kit?

ovulation test FAQ To determine when to start testing, you must first determine the length of your menstrual cycle. The length of the menstrual cycle is the number of days from the first day of menstrual bleeding to the day before bleeding begins on the next period. Determine the usual length of the menstrual cycle over the last few months. Then, refer to the Cycle Chart to determine on which day of the menstrual cycle to begin testing.

Q: How long after my LH surge will ovulation take place?

ovulation test FAQ Generally, ovulation will take place 12-48 hours after the LH surge is first detected (using afternoon urine samples), though 36 hours is considered to be the average length of time following the LH surge.

Q: When I get a positive on an ovulation test, when is the best time to have intercourse?

ovulation test FAQ To increase the chance of conception, it is best to have intercourse the day of the LH surge as well as following three days after.

Q: Does the appearance of faint 'test band' indicate an LH surge?

ovulation test FAQ A faint line (or a faint positive test band) does not indicate a positive result for an LH surge. While the presence of a faint line on a pregnancy test may indicate a positive result, a faint line on an OPK is always negative.

Q: Does taking my basal body temperature tell me the same thing as an OPK?

ovulation test FAQ Basal Body Temperature only tells of your LH surge after it is over. That is why the BBT method cannot predict the LH surge. Ovulation tests will tell you - with pinpoint accuracy - when your chances for conception are greatest.

Q: Can OPKs be used as contraception devices?

ovulation test FAQ Ovulation tests are designed to help facilitate pregnancy. They are not recommended for contraception.

Q: Can clomid interfere with test results or cause false positives?

ovulation test FAQ Clomid may cause false positives if you test for ovulation too early in your cycle. Please consult with your doctor about how to use OPKs in conjunction with Clomid - or other fertility and prescription drugs.

Q: Does a light test line and a dark control line indicate a positive result?

ovulation test FAQ Ovulation tests are unlike pregnancy tests - especially when it comes to interpreting results. The results are only positive if the test line is equal to or darker than the control line.

Q: I had a positive result yesterday and today. Does that mean there is something wrong?

ovulation test FAQ Such results may indicate that your the tests detected the LH Surge on the way up and again on the way down.

Q: What if I experience a BBT thermal shift but the ovulation tests failed to detect my LH Surge?

ovulation test FAQ It is possible to miss the surge. If you have a test line that is fairly dark one day then very light the next, you may have missed the actual surge. If your thermal shift occurs, you probably ovulated. It may be a good idea to test twice a day when you feel that you are close to ovulating. Another possibility is that you didn't hold your urine long enough (resulting in a diluted sample).

Hi, today morning I did ovulation test and also pregnancy test. The ovulation strip showed darker test line than control line and the pregnancy strip showed faint test line. What does this indicate? And also we had sex last night and I didn't urinate between after sex. So, does this has any influence on the test?

I have irregular periods, so I started taking an ovulation kit. I got a positive LH surge on Wednesday. I had sex the Sunday that started that week than again about 27 hours AFTER my LH surge was detected. What are my chances of becoming pregnant?

I have a 32 day cycle. I have been testing since I finished my perieod because I was so paranoid that I would miss the positive result. I have been testing, testing, and testing and no luck. I am losing hope already because all I get are faint lines and I tested today and now the lines are really really light. So I dont understand why the test did not match the control line. However, although I did not get a positive result I still had intecourse just in case I missed the positive result. If it does not happen this month I will by a digital test so I dont have to guess anymore. I should have done this since the getgo. ugh! I am so mad at myself. Good luck ladies!!!

You can use an OPK can be used as a contraceptive, in some small shape of form. You see the days you ovulate so you know when not to have sex.

Hi everyone, I have a question...I have PCOS, and have taken my first cycle of clomid this month CD 3-7 according to when my flow was heaviest. (I spotted on Sunday and Monday but on Tuesday it was REALLY there, so I started clomid on Thursday). I have been using OPK's and so far I dont think I've had a +++OPK. I know its common to have two lines, but I was just curious do they get darker and lighter? Like for a few days it was getting darker(Never darker than the control), and the last two days the test line has been SUPER light. Is it possible I missed my surge? I have googled it a million times and I'm having no luck finding an answer, so maybe someone who has experienced this can help??? Thanks!!

if the surge line on your ovulation test gets darker each day does that mean your getting closer to ovulation? or a faint line or no line means negative no matter what?

I want buy ovulation test

I just got smiley at my OPK today 2 pm. The last we BD was on 20th. So we will BD today onwards. Have i missed the right timing so we still have chance to conceive? Someone please advise.

To Anonymous March 11,2011. You should try the Clear Blue Easy digital ovulation kit. It shows a circle when there is no LH surge detected and a smiley face when the LH surge is detected. It comes with 20ct sticks. Its more simple than reading the lines. and the best time to test is around 2-8pm. Thats when i saw my smiley. Gd luck to you.

Hi, I had the implanon in for 11 months but had it out on 10th February and had a bleed from 26th to 1st march so only 4 day bleed. Me and my partner would really like a baby. I bought some ovulation tests but not quite understanding them, when would be the best time for me to test my ovulation?

Any advice would be much appreciated Smile
