What heavy periods can involve
Heavy menstrual bleeding is common and frequently dismissed, partly because there is no easy way to describe it. People compare their periods to a standard they have never seen, and are then asked in an appointment how heavy is heavy. Flooding, clots and changing protection hourly are the details that answer that question, and they are the ones easiest to leave out.
The knock-on effects are the part that gets missed entirely. Fatigue and dizziness from low iron, and the planning around leaks that decides what you wear and where you go. Written down as it happens, a few months of that becomes something concrete to hand over rather than an impression you are asked to summarise.
