Quoting Dr. Mrs. The Monarch:" Hey ladies, another thread reminded me of this, but I know a lot of you reborn progesterone support... ... [snip!] ... support... Did I hear from some of you all that even on support you don't always see an increase in your blood values?"
That's right. If you are taking the supplements vaginally, you won't actually see the rise on a bloodtest, because the supplement does not get absorbed all the way to the bloodstream. That doesn't mean it's not working, it is just right where it needs to be.
I took 200 mg twice a day during my LP and once I found out I was pregnant my progesterone level was tested and was 9. They upped me to 3 times a day just to be safe, but they told me that's how it works. My son is 5 months old and I really believe he wouldn't be here if I hadn't been on the supplements, given how low my natural blood level was.
