So testosterone peaks as well because testosterone is important in fertility as well.

The second half of our cycle, we have a rise and fall of those hormones as well.

Just before our periods, if we don't become pregnant and don't conceive, then there's a massive decline of those hormone levels.

So we know that the hormones work on every cell, organ, tissue in our body.

So when we have changing levels of those hormones, it can cause a myriad of symptoms.

We know that because those changes in hormone levels can cause perimenopausal symptoms, menopausal symptoms, but they can also cause symptoms throughout the menstrual cycle.

So on Balance app and also throughout our clinic on my website, we have a symptom questionnaire that is important for anybody that has hormonal changes.

It's not just a menopause questionnaire.

It's a questionnaire that anybody can use to just think about any of those symptoms on the questionnaire can be related to changing or low hormone levels at any time of a woman's life, including during her menstrual cycle.

So we all are used to seeing graphs of how our hormones change throughout our menstrual cycle.

But there's this lot of confusion and I want to hold something up, which for those who are just listening, I'm going to talk through as well.

But if you see here on this picture, this is what hormone levels, the Easter dial being read,

and progesterone being green, this is the start of our menstrual cycle.

There's a peak in ovulation.

And then the second half of our cycle, there's an increase in estradiol and an increase in progesterone.

But those graphs really are not to scale.

And that's really confusing because actually, if you look at the levels of progesterone in the luteal phase relative to estrogen, this is what happens.

The progesterone is really high and then falls off a cliff very quickly.

And so it's hugely more significant and you could say more important than estradiol.

And in the luteal phase, this change in progesterone level can really trigger a myriad of symptoms for many, many women.
