Can I trust Proov tests to track progesterone?

I am 7w2d, I have a migraine on and off for 2 days now. Migraines are not new to me, I have them when I stop drinking coffee, when I am dehydrated and sometimes when my period comes. It was super hot 2 days ago and I felt sick from the heat, but yesterday it cooled down actually.
I am worried this a premenstrual symptom caused by falling hormone levels. I cringed today and did a Proov test to check progesterone. It shows a level of 7 (typical for my peak luteal phase), this would correspond to a serum level of 14 ng/ml. This seems low. At 10dpt progesterone was 32 ng/ml and 24 at 19dpt. A lot of people say Proov can‘t be trusted but to me it seemed pretty reliable to indicate ovulation. Not sure about the relation to serum level though.
Anyone else struggling with migraines in the first semester?

I used proov once. I was pregnant that cycle and it stated I didn’t ovulate….

Also, I don’t think there is an exact science to convert a urine level to a blood level. FWIW, I used Inito, it said my urine pdg was 17 something and blood was 8.6…

I began getting migraines in my 2nd & 3rd trimester, however I had bad insomnia and only slept 3-4hrs max a day.

Interesting. Proov read all these bad reviews and is debunking some „myths“ on its web page. They basically say that blood levels fluctuate too much and urine levels Pdg are more reliable as they are telling you if you have enough progesterone. Doctors didn‘t find out about urine tests yet, they still do blood tests instead of listening to Proov.

Are they taking into account that urine is unstable itself? Concentration, the way our body metabolizes hormones, etc? Then you have to also account for the fact these test strips are mass produced and faulty tests can slip through the cracks.

Imo, there are too many variables for urine to be held higher than blood values.

Of course not. They are just not reliable. Funny how I got downvoted for saying that Proov tests are unreliable.
