Our hormones are constantly changing in response to our external and internal environment. The reproductive hormones follow a general pattern called the menstrual cycle for most people while they're of a certain age range. Having balanced hormones is a colloquialism for meaning having hormones that don't cause us any trouble. It has very little to do with the actual levels of our hormones we might expect to see on any test results.
After months of cystitis and thrush, I gave up the contraceptive pill for good... I was about 19 at the time and I’d heard from a friend that it might be the cause, and they were right. So I started using my first ever hormone-free contraceptive (aside from condoms): the fertility awareness method (FAM).
