Saliva test results in my journal entry

I was hoping that b/c ya'll have so much experience dealing with this stuff, you could maybe take a look at my detailed saliva list journal entry and share your comments. While I orginally didn't do the saliva test for fertility reasons, I'm concerned now that my levels are whats causing me to not get pregnant even though DH and i have unprotected sex. It appears to me now, that all these times i had pregnancy symptoms but no pregnancy, that I was possibly conceiving and just not implanting b/c of my progesterone levels being low when they should be high and high when they should be low (this is what my doctor said).

I'd really appreciate your time in this! Thanks ladies!
