I'm going to test again this afternoon, just to see if it is darker, I'm just not sure what to consider this one. (More on this below. You interpret or read the result by comparing the colour intensity of the control band to the test band. • Please contact your nurse for assistance in determining when a pregnancy. At this time, when the surge is detected by a dark test line, you should ovulate within 12 to 48 hours. The ClearBlue Ovulation Predictor Kit is a similar product to the First Response Kit and works. An OPK is considered positive when the color and intensity of the test line matches or is darker than the control line. Read result in 3-10 minutes. The surge line is darker than the control line. How does it work? The function is similar to the digital ovulation kit as described above. I took an OPK at 13dpo with this pg and got a SUPER positive OPK (test line darker/bolder than the control line). 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. I tried this with my last pregnancy and I didn't get a true positive on the opk until my hcg levels were over 1600 - at that point, my hpts were, of course, blazingly positive. If so, ovulation should occur in 1-2 days. Test line clearly darker than control line. Test twice when the line starts getting darker. When the test line is as dark or darker than the control line we can know it is positive. You may have your test line darken gradually until you get a positive, or you might surge suddenly and go from a faint line to a dark line in no time. The test line is not darker than control line, but very very close. You will need your test line to be darker than or as dark as the control line. A second line that is as dark or darker purple as the control line indicates your LH surge. I know that PCOS and Clomid can both affect OPK results but I still want to keep track of them. If the results line is a lot lighter than the control line what does that mean? I have had this result 2 days in a row with the control line slightly darker today. Does anyone have any ideas what this could mean? Seems early to have such a dark test line and my dates are definately right?. How to use? First, you pee into a cup, and then dip the strip for 3 seconds. Could you actually be pregnant now? Opk will show posative results when at the of the 2ww if pregnant. The results are only positive if the test line is equal to or darker than the control line. I guess that on CD13, the test was detecting some LH but not quite as much to make it positive but there was enough on the next day. After 5 minutes, examine the test line, if it is as dark or darker than the control line, you'll ovulate in the next one to two days. Even the ones that have a relatively darker line are definitely negative. But yes, the darker the line, the stronger the level of HCG in your blood, and having higher HCG levels is a good sign of a strong pregnancy starting off. For an ovulation test to be positive, the test line must be the same or darker than the control line. I have read that you can use OPK's to predict pregnancy, but only if you already know you are pregnant and are doing it just for fun, because 2 lines show up frequently. Be sure your test is 100% positive before you inseminate. She sent me a picture of the first BFPtaken at 18 dpo. OPKs can sometimes be confusing to read because unlike a pregnancy test they will most likely have two lines even when not positive.
