I'm by no means an expert, but I thought that I would list some websites that might point you in the right direction if you're wondering if you, yourself have a low-progesterone/estrogen dominance problem. These are sites that pushed me and my sister, W, in the right direction. I do not recommend self-diagnosing, but I do encourage you to do your research and then definitely seek out a doctor that will take the time to take your blood on the correct day (usually anywhere between days 19-22 of your monthly cycle, charting is a good thing to do so you know where you are exactly in your cycle, even if you have a history of previously having very normal cycles) and test it for your hormone, adrenal gland, pituitary gland, and thyroid functions (all of which can have a hand in low progesterone and other hormone issues).
I hope that if you stumbled across this blog while searching for information on hormone issues, that you will soon find an answer that restores your body to wholeness. God created each of us to be healthy and whole in these bodies that we live in; so, don't give up, there is an answer for you out there!
"Beloved, I wish above all things that you may prosper and be in health, even as your soul prospers." 3 John 1:2 (American King James Version)
