'My last period started Monday.'
In an appointment, 'my period is regular' can shut down a useful conversation before it starts. 'I was usually 30 days and I've been around 26 for several cycles' gives your provider a specific history to consider.
You don't need a perfect tracking system. Even a rough month when you first noticed the difference can help explain the timeline. The important distinction is between noticing a change and deciding what caused it. A shorter cycle may be one piece of the perimenopause picture, but it isn't a diagnosis, and one early period doesn't settle anything.
If you've been telling yourself 'I'm regular' while the numbers keep changing, look at what your own history actually says. That's the starting point for a more useful conversation with your healthcare provider. The Cycle Guide goes deeper into how to interpret the change and what to consider next.
