As always, if you run into any trouble, let us know at


The menstrual cycle is more than just your period – it’s a complex ebb and flow of hormones that make your reproductive system function. But did you know that hormones are also crucial to countless other processes in your body? As you slam on the brakes to avoid a car collision, your adrenal glands pump out the hormone adrenaline (epinephrine) to help you act quickly. And melatonin helps to ensure you get a good night's sleep.

Love it

It works very well and is very helpful if you are not good at dates. It will give you a notification when it is honing the start again and it is with me always 3 days before I am in my period.
