A cycle that has shortened from your usual 28 to 30 days down to 23 to 25 days for two to three months running is a real change, not just normal month-to-month variation. This pattern often comes from a shift in ovulation timing, driven by stress, a
thyroid change, or a recent change in weight or routine.
Next Steps
Keep tracking cycle length and flow the way you're already doing. Ask for a
TSH test and a basic hormone panel, and see a gynaecologist if the short cycles continue past another month or two.
Health Tips
Get checked sooner if any cycle falls under 21 days, bleeding becomes heavier or lasts longer, or you get pain between periods.
