And actually, when is it that people should go and get the help and support from their GP?

Yes, that is a great question.

And the answer is that is going to be really different for every single woman.

So if we think about a normal menstrual cycle, in a normal menstrual cycle, our oestrogen goes up and down twice.

and then we bleed.

Our progesterone only goes up and down in the second half of the cycle, and then we bleed.

So if we think about all the possibilities of what's happening, so let's start with bleeding.

Again, what kind of questions are the kind of right things to be asking?
