That makes what you remember the main thing a doctor has to work with, and memory blurs months of ups and downs into "on and off". A useful record holds four things: the days you bled and how heavily, each symptom rated mild, moderate or severe with the time, how you slept, and anything that changed, such as a new medicine. Two or three cycles of that turns a vague worry into a page a doctor can read in a minute. [How to track symptoms and prepare for your appointment](/topics/tracking) How we work ### Sources you can open yourself Every health fact on Peri Signals links the page it came from: the NHS, ACOG, NICE, MedlinePlus, The Menopause Society, the CDC or a published study. We describe symptoms and say when guidance suggests seeing a doctor. We do not give treatment advice, and nothing here ranks products.
