- •Try warm baths or showers for comfort (unless waters have broken)
- •Keep your hospital bag in the car and review your birth plan
- •Eat nourishing meals and stay hydrated
- •Contact your care provider about any signs of labor (regular contractions, water breaking, bleeding)

Looking ahead
You may go into labor any day now, or you may be one of many who goes past the due date—both are completely normal. Your care provider will discuss next steps if you haven't delivered by 41 weeks. Trust your body and reach out to your support team when you need it.
