## Description

Track your cycles in our FREE app, designed for use with Clearblue Advanced Digital or Digital Ovulation Tests. Identifying your most fertile days is the best place to start. The Clearblue Digital Ovulation Test (Prueba de Ovulación Digital) is more accurate than calendar and temperature methods at predicting the most fertile days[1]. With Clearblue Digital Ovulation Tests, you can accurately identify your 2 most fertile days to maximize your chances of getting pregnant naturally. Each ovulation test kit includes 1 digital reader and 40 individually wrapped ovulation test sticks that track LH (luteinizing hormone), the hormone that surges just before you ovulate. The test sticks have an absorbent tip that can be used directly in your urine stream or dipped into a sample of urine in a clean, dry container. When you see a line with a surge in the result window, you know it’s your best time to try for a baby.

Review: Convenient, mess free, good price for the value, and it works! - I'm not one of those reviewers who will write that they got pregnant the first or the second month they were using this ovulation kit, but I can verify that this test works. When I first got this kit I also started charting my temperatures just to verify that I ovulated (the ovulation prediction kits can only detect that you are about to ovulate, but they can't confirm that you actually ovulated). It was my first experience using an ovulation kit, and I didn't trust it 100%. The first month I was using this kit, it detected my ovulation on the fifth day of testing. My temperature rose two days later and it remained elevated through the end of that cycle indicating that I ovulated. The second month this test detected ovulation the day before the spike in my temperatures. In other words, the test works, and it is accurate in predicting ovulation, which puts my mind at ease and probably means that I can stop charting my temperatures. This is great news because I really like using this test. I find it to be very convenient and mess-free. It comes with 20 test sticks and one test result reader stick. It is very easy to use, and if you want to carry it with you to work for testing during the day (which you don't have to do because testing in the morning before you leave the house is sufficient), you can. Convenience was very important to me, and I didn't want to stress and fret too much about testing, peeing in the cap, interpreting the results, etc. This test gives me just that. You insert a test stick into the reader, pee on it, and then three minutes later you have the result (smiley face for ovulation, empty circle for no ovulation). If your cycles are relatively regular, this is a great test to use. I used five sticks in the first cycle (you start testing 17 days before your expected period), and four sticks the second cycle, so basically this one box will probably last me close to four cycles which is a good value for the money it costs. When you are done with the test just press the "eject" button, and discard the testing stick. The result will first disappear after about a minute or two from the time it is first displayed, but when you eject the stick the reader will display the result again for a short while which is great if you want to quickly jump in the shower or get interrupted immediately after testing. In summary, using this test can't guarantee that you will get pregnant as soon as you start using it, but it is accurate in predicting ovulation which is obviously one of the most crucial things for getting pregnant and for gathering information about your cycles.
Review: WORKED FOR ME ON THE 1st TRY AFTER TTC FOR 16 MONTHS!! - Let me start off by saying I had a tubal pregnancy (unplanned) which lead to complete removal of my right tube in July 2009. We started trying for baby November 2010. It was a little disappointing at first and then proceeded to be very frustrating as Aunt Flo kept rearing her ugly head each month (my cycles are very regular btw). I was going off of ovulation calenders, the small microscope that detects ovulation through saliva, and eventually bought cheap ovulation strips where the line has to be as dark or darker than the control line. Those are all just plain stupid and very inconsistent, IMO. I did have a hysterosalpingogram (HSP January 20th, 2012. It's a procedure where a catheter is inserted into your uterus & ballooned open. Dye is then shot into the catheter to see if the fallopian tubes (or in my case tube) have a clear path to the ovaries. Now, my doctor did said there could've been a small mucus membrane(s) that's blocking the path(s) but when dye is shot into them it can clear the path(s) for fertilization. Anyhow, i was skeptical but purchased this anyways because a friend of mine said she knew a lady that got pregnant with in 2 months on this OPK. My smiley face came a day or two later than what I originally thought my ovulation would be (Day 18/19). I tested at the same time (about noon) the following day (Day 19) since I know ovulation only takes place for approximately 24 hours, another smiley! I wanted to make sure it wasn't a false reading so I tested again later that evening and my smiley was gone, which was a good sign! I took a pregnancy test on the 1st day of my missed period (a Tuesday), negative. I was not feeling any different & expected it to come within the next day or two. I still had not started by Saturday (St. Patty's Day) so I took another pregnancy test that morning and got my POSITIVE!!! I had my first doctor's appointment yesterday and we're due November 19th!! I am still in disbelief but super excited. I am not sure if it was my procedure that helped us or these OPK. I give credit to both actually since I was 2 days off every month & this OPK confirmed with a simple reading. I have a friend who tested too & she got her smiley face yesterday!! I will keep you all posted on her results in a few weeks... TIPS: - don't make these tests any harder than they are, they're simple in fact! - insert the test strip into the reader with arrows facing each other - wait for the blinking in the test window (blinking means it's ok to test & the strip is inserted correctly) - i would recommend peeing in a cup then dipping (if you pee directly onto the stick, you could have too much or not enough urine for the test to read, which will result in an error message) - do not use your 1st pee of the day to test. OPK are not like pregnancy tests. The LH surge is best detected by the 2nd or 3rd pee of the day - make sure you have at least 2-3 hours in between times of urination so it is somewhat potent for the test - best times to test are between 10am - 10pm GOOD LUCK & BABY DUST TO YOU ALL!!!

I thought these were going to be too complicated but they were super easy to use! When it detects your peak time, it displays a super cute smiley face! It comes with 10 and I only needed 4 before to determine my peak window! Definitely would suggest this product if you’re looking to accurately monitor your cycles! 🙂
