"Peak" fertility the first time I used the test, on day 9 - is this a likely error?

I'm using the ClearBlue Advanced Digital Ovulation Test (purple). My period ended 3-4 days ago, and I used the ovulation test for the very first time today (Day 9). I got a Peak fertility result, which doesn't seem accurate to me. Is it possible to reach peak fertility at this point in my cycle? What are potential causes of a faulty "peak" result? I saw in a frequently asked questions that it is impossible to get a "high" result the first time you use the test; is it possible to get a "peak" result the first time you use the test? Especially if I'm this early in my cycle?

Thank you!!

Hi Meghan, thanks for messaging us. If you're having a shorter cycle than normally then Peak Fertility may be displayed correspondingly early. Peak Fertility may also be displayed earlier if you are pregnant or have recently been pregnant, taking certain medications or if you're having certain medical conditions. If none of these apply and you've performed the test correctly we would recommend having intercourse on the day Peak Fertility is displayed and the day afterwards. If you have any concerns you should see your Doctor. Hope this helps!

Could clomid cause false positive on the kit?

Hi Sangeetha, 

Clomid will not affect the accuracy of your Peak Fertility result (solid smiley face), however Clomid can cause an increase in estrogen levels therefore High Fertility (flashing smiley) may be affected, you may see an increased number of High fertile days.

We hope this helps,

Regards,

Sally

Hi, I had the same case . My normal cycles are 32 -34 days. Today on day 12 of the cycle, I used the clear blue advance digital test and got a peak smiley. I take prenatal vitamins the night before and took the test first thing in the morning. I do not take any other medicine. Does this seem accurate? Please advise

Hi Shruthi,

Prenatal vitamins should not interfere with you test results, please check you are suitable to use the test this information can be found on the side of the box and in the leaflet. If you are suitable to use the test your result will be over 99% accurate.

Meghan,  I just used the ClearBlue Advanced Digital Ovulation Test (purple) today for the very first time.  It also showed the "peak, on my very first use, on day 7 of my cycle.  I have read the response by ClearBlue above.  None of the causes of a faulty "peak" apply to me.  Just wondering what the outcome was of your situation.  I'm still not sure that I could truly be peaking on day 7, and the very first use.  Thanks!

Hi Sarah, this is Meghan. It turns out that I just happen to ovulate very early in my cycle, which is why the test showed "peak" so early on my first use. A few weeks after I wrote that post, I found out I was pregnant. Then I had a miscarriage around 8 weeks (baby was measuring 5). We tried again a month or so later -- I used the Clear Blue Advanced Digital Ovulation test, and once again it showed that I "peak" early. I got pregnant that time, and just gave birth last Tuesday to my son. So I would say that you are just ovulating very early in your cycle. Best wishes!

Hi this is a long shot since this was written 2 years ago. But I just had a miscarriage at 6 weeks, 3 weeks ago, when you used the clear blue after your miscarriage did you wait to have a cycle and then use it. Or used it when your HCG levels went back to normal? Thanks !

Hello, I had a missed miscarriage at 8 weeks baby measured 6.4 weeks. I had a d&c the next day and decided to count that as day 1 of my cycle as I only had very very light spotting. I had 3 days of lows on days 6, 7 and 8. The next day (DAY 9) I got a PEAK! Does this mean I am ovulating? I understand that hcg can throw a wrong result but I had 3 days of lows so surely this can't be the case for me. Any advice please clear blue? ?

We are sorry for your loss.  A recent pregnancy in the last 9 weeks can affect your results - even if you had low results first as the Holder adjusts its sensitivity across a cycle of testing.  We recommend you wait for two cycles before using our tests - you can keep the Holder and unused test sticks for future use.

I have a 30 day cycle. I’m using cb advanced kit.

The first month, I took the ovulation test sporadically on 3rd,6th,10th day and got empty circle. Then on day18 I got a peak fertility(solid smiley) directly.

Next month, I took clomid from day 4 to day 8.

I took the ovulation test for the first time on day 13 and got a peak solid smiley face directly. I took a blood test immediately to confirm(because I was expecting ov on cd18) and the Blood test showed no lh surge and elevated progesterone meaning that my ovulation has already taken place.

Not sure why the ovulation kit has been misleading.

Does it make a difference in the accuracy if the ovulation tests are taken in middle of cycle?
