She fell pregnant straight away and has had no fertility issues there.

But this test and what it tells you and what it doesn't tell you

it feels like is everywhere.

And so I wanted to ask Dr. Tessa, whose research is really about what this test is, what it isn't, and what the marketing of it is, so that hopefully everyone listening to this goes away getting a bit more of an understanding as to whether or not you can actually test your fertility.

Without further ado, here's Dr. Tessa Kopp from the University of Sydney.

Tessa, thank you so much for joining The Daily Oz today.

Thanks so much for having me, Sarah.

So certainly in my friendship group, the discussion of fertility, where to find information has somehow come out of nowhere but is everywhere.

And I wanted to chat to you today about understanding what you can actually do to test your fertility and also where to get, you know, credible information from.

So I guess as a starting point, can you just give a really rudimentary example

explanation of how a woman's fertility actually works, because otherwise it can be a bit challenging to know what's actually right and wrong.

We learn how not to fall pregnant.

I don't know that we ever learn the opposite.

No, you're right.

Yeah, that's my mind.

Yeah.

Blows my mind.

Because it is a limited window.

We're told so often about how easy it is to fall pregnant if you are not trying to fall pregnant.

But if you are trying it, there's actually a very limited window where you can fall pregnant.
