Progesterone test is negative??

Has anyone tried these? Got bfp this morning. According to this I’m under 5 for progesterone?? anyways there checking my bloods today. Hcg and progesterone check. Wonder if that’s why I miscarried. Why the hell do we have to have three losses in a row for them to offer it?? I have not. That was my first natural one last month. I’m glad I bought these so I could take this into my own hands!! Keep you guys updated on what they say so we know if these tests are good or no good. 🌈👶 awaiting you
