I have started to use Proov's pdg test. This is how it works if you are interested.
There are 6 days to take the tests.
Day 1 (Follicular phase, baseline pdg test): the first day after your period ends or on CD5. Expect this test result to be negative, as this provides an important baseline result to which you can compare your future results.
Here is what I found regarding the importance of the PDG baseline tests.
"To understand what “elevated” means for you, we first need a good idea of what your natural levels look like so that later on we can tell whether or not your PdG levels reached an adequate level in order to allow for the best possible chance at conception.
Additionally, baselines can help us confirm whether or not you ovulated, in the event that your 7-10 DPP tests weren’t quite positive. If there is a significant enough change in intensity between the test line on your baseline test to your 7 DPP test — meaning your 7 DPP test is significantly lighter — then we can confirm that ovulation did in fact occur."
Day 2 (Fertile window): the day when you detect peak fertility
Day 3 -6 (Luteal phase): 7dpo - 10 dpo, 4 days pdg testing. Your levels cam fluctuate from day to day.
Positive: If only a single line shows (the "control line"), your test is positive, indicating elevated PdG.
Negative: When two lines appear, the result is negative, indicating PdG levels are not elevated enough for a positive result.
Note: A baseline reading will typically be negative, although the test line may be faint.
Successful ovulation: Positive results during testing window (sustained PdG levels during the testing window) indicates a successful ovulation this cycle.
You must use FMU and I dip the test strip in the cup for 15 seconds and wait for 10 minutes then I use the Proov app to read the result.
I used it for the last cycle (3/4/24 - 6/5/24) starting from dpo7. So, I didn't have the baseline.
As you can see in the images, CD25 (8dpo) shows pdg 5.5 which means it is positive. Anything below 5 is negative. I had negative results for 7dpo, 9dpo and 10 dpo. My guess is I did ovulate successfully however my pdg level was not enough to support this pregnancy so CP happened. This is only my guess and I could be wrong. However if I have the same or similar test results for this cycle, then unfortunately end up with the 2nd CP, well, that would tell me something about insufficient Pdg and that is something I could take to show to the GP.
This cycle I started to test Pdg on CD8 (14/5/24) and got the baseline level pdg 0.3. Today is the LH peak day so I tested again and I got pdg 1.5. Will test for the third time for 4 days from 7 dpo.
Yes, testing HCG on 1 dpo and starting to see the shadow on 10 dpo then spotting a super super super faint line is definitely exciting. Watching it getting darker then fainter is also heartbreaking. So, only testing if AF does not arrive is a sensible and smart move.
I am at the stage that if CP happens again, then I would be more prepared to handle this. I will have more data and talk to the GP to give me Pdg when I get pregnant again in the future.
After 2 MCs, I am still cautiously hopeful. I look forward to hearing good news from you! : )----
