If you struggle with infertility and need to confirm ovulation, the Ovulation Double Check Home Progesterone Test for Fertility and Ovulation Tracking can help. According to their website:
The Ovulation Double Check® test is an FDA compliant and patent-pending in vitro diagnostic device that measures the presence of the Progesterone metabolites in urine. Progesterone is very low in the female body the first half of the menstrual cycle. When the ovary releases an egg, ovulation occurs and the ovary starts to produce Progesterone at a significantly high concentration. Therefore, Ovulation Double Check® tests should be taken after you believe ovulation has occurred to “Double Check” if ovulation has occurred.

The Confusing Part
When using these tests, you have to turn off the part of your mind that is looking for 2 lines to equal a positive result. These tests do not work the same as OPKs and HPTs. If you see two lines—even if one is the faintest second line you’ve ever seen—this means your progesterone level is registering as less approximately 10-12 (based on the images in their clinical research), and the result is negative. So just keep that in mind when you go to use these. Two lines are not good… you just need one to have a positive result.
What These WILL Tell You
If your progesterone level is rising. Taking tests several days in a row should show a progression of progesterone in your system, or will show if part of your infertility is, in fact, a luteal phase defect (low progesterone). That is precisely what these tests confirmed for me.
If your progesterone is declining. Let’s say you’re toward the end of your cycle and you’re getting negative pregnancy tests, but want to be absolutely sure you’re out for that cycle… these can tell you if your progesterone is declining. If you see positives and then it leads to negatives, it’s very likely your progesterone is declining.
If your pregnancy may need supplement support. If you ARE pregnant and concerned about progesterone deficiency, this can tell you if you’re dangerously low. Pregnancy truly needs a level of at least 15 (preferably 20) to be self-sustaining without supplements, but if you’re early in your pregnancy and waiting to get in to see your doctor, these can tell you if your level is low, and you can probably get a script for Progesterone called in quickly.
What These WON’T Tell You
An exact number. These can only tell you up to a certain point, according to the clinical research images on their website. It would be awesome if they came in a higher sensitivity level, but these are an excellent start and can at least confirm ovulation in the meantime. That’s all these are meant to do – confirm ovulation. According to their website, they are working on quantitative progesterone tests that may be available sometime this year! I don’t know about you all, but I’m super excited about that!
If you’re going to miscarry. Progesterone deficiency is one of those controversial subjects in the fertility world. Some doctors absolutely do not believe that progesterone is linked to miscarriage, while others feel like there is enough scientific evidence to support that it is linked. Either way, the only way to know for sure if your progesterone level is supportive of a healthy pregnancy is to go get a quantitative blood test completed by your doctor at the same time as your HCG beta test. These tests are only meant to confirm ovulation. If your level is low, it doesn’t automatically mean a miscarriage is on the horizon, so just take a deep breath and call your doctor if your test is negative (two lines, not one).
My Personal Experience
I took 4 tests for this blog post to show a progression of progesterone in my system post-ovulation. I took them at 1 DPO, 8 DPO, 10 DPO, and 11 DPO. The reason? After that 1 DPO test, I started to question whether I had ovulated when I thought because I continued to have ovulation symptoms for several days following (I thought I ovulated on CD 18 but it may have been closer to CD 21… YAY for PCOS). Then, I noticed that I didn’t feel progesterone symptoms yet (I’m very sensitive to progesterone). It wasn’t until 8 DPO (or heck, maybe 4 DPO if I ovulated later) that I started to feel slightly different. The tests did align with what I was experiencing. You can see a visible difference in the lines between 1 DPO and 8 DPO. You can see that there were obviously trace amounts of progesterone in my system because the second test is lighter than the one a week prior. But… it wasn’t light enough. It was still considered negative.
I tested again on 9 DPO and the result wasn’t much different. The lighting was slightly different so it looks a little more negative than from 8 DPO, but in person, they were pretty identical.
At this point, I knew that the cycle I chose to do this review was the cycle with weak ovulation (of course). I’ve been having excellent results with essential oils helping me ovulate (you can see more about that on my Instagram highlights), but usually, when I ovulate I’m having to supplement if I think there’s a chance of pregnancy because my luteal phase still isn’t right. These tests confirmed this.
So… for the sake of science… and knowing I’m not pregnant this cycle because of bad timing… I decided to take one 200mg progesterone supplement on the night of 10 DPO to see if it showed up on the test the next morning. Seven hours later, here is the result:
Just one supplement made a visible difference. This proves that these tests do work. I wish it was my own natural progesterone causing a positive result, but seeing that these tests actually work was enough to make my heart happy.
Do I Recommend the Ovulation Double Check® Test?
If you don’t like to take your temperature every day and don’t chart your cycles, yes.
If you have the budget, absolutely.
These are a little more expensive than most ovulation tests, but they are extremely convenient. Also, as someone who used to chart my cycles and no longer does because I got tired of ambiguous results due to inconsistent wake-up times, these are very helpful. I can’t even begin to express how much that means to me. As a woman who struggles big time with PCOS, confirming ovulation, and luteal phase defects, these will take so much guesswork out of TTC. Yes, it’s yet another thing to collect pee for, but if you need peace of mind, these are certainly worth trying out.
And let me just say that when they do release the quantitative tests, I’m definitely jumping on the train. Peace of mind when TTC during infertility is priceless.
