Use a heating pad or warm bath to help cramps and flow feel more manageable
Stay hydrated
Get regular light exercise if you feel up to it
Consider over-the-counter NSAIDs like ibuprofen or naproxen if you can take them safely, as they may reduce bleeding and cramps
Ask a healthcare professional about hormonal birth control options, which can sometimes make periods shorter or lighter over time
Ask a healthcare professional about tranexamic acid if you have heavy bleeding
Avoid smoking
Get enough sleep
Seek medical care if bleeding is very heavy, lasts longer than usual, or you have severe pain, dizziness, or fainting
