Proov progesterone test

I decided to buy proov because I have had symptoms of low progesterone. After three years ttc we finally conceive a few months ago and had low levels of progesterone they started me on Vaginal suppositories right away but I still lost that pregnancy.

This cycle I start the suppositories right after ovulation the proov test was positive at 7dpo but there’s a faint second line today at 10dpo meaning my progesterone dropped to soon? Even with the progesterone supplement 200mg nightly

Has anyone else had this problem? If the progesterone supplement doesn’t help I don’t know what help to do
