What is the optimal estrogen level during the follicular phase of your cycle if you are TTC?

Good morning,

I have tested "positive" for estrogen dominance but that was on Day 6-7 AFTER ovulation. I;m trying to figure out what my estrogen levels should be during the follicular phase of my cycle.

When I google this online I get a wide reference range which doesn't help.

I'm using a high end fertility tracker (Mira) for the first time and testing every day right now at the same time. It's supposed to be very accurate if used correctly. I've had friends get preg using the Mira tracker after months and months of failing to get pregnant.

Currently the tracker shows that I'm currently 3 days from ovulation and my E3G level today is 305 ng/ml and my LH is 1.6 mIU/ml. I'm on Day 10 of my cycle and approximately 3 days from ovulating.

Is 305 ng/ml normal around the time of ovulation or should it be lower or higher? Is there an optimal number for ovulation?

I'm frustrated that I can't get a definitive answer from my doctor. Hoping someone can help.


P.S. Also what does this mean for someone who is estrogen dominant like me? If my estrogen during the follicular phase is higher does this mean I'm more likely to be estrogen dominant?

​Hi Maude

I am most surprised that the doctors or lab didn't explain this to you. The Hormone Testing page gives all the test results and what they should be at certain times of the month.​ ​Our hormone levels change during the month as shown on the page.​

If you aren't using progesterone cream, please consider using it. The ​Pregnancy page will explain why. I don't know much about Mira so I can't comment on that. ​

Estrogen Dominance causes all sorts of adverse things as mentioned on the page. Progesterone is needed to balance it. If progesterone levels are low you could have problems with TTC. Please read the How to use Progesterone Cream page.

What is your Vitamin D3 level? A deficiency reduces the benefits of progesterone and is connected to every single functioning cell in our body making​​ it vital. It is extremely important to the mother and her unborn child.
