What do I do if my water breaks?
In the movies it is a flood and a taxi chase. In real life the whole first step is one phone call.
The short answer
You call, they guide.
If your water breaks, call your ob-gyn or obstetric care provider and follow their instructions. That is the whole first step, at any hour. Waters breaking is also just one of several ways labor can begin, and the signs can arrive in any order.
What's going on
One of several opening moves.
Labor rarely follows the script. For some it opens with waters, for others with backache or contractions that build slowly over hours. The reviewed guidance lists the full cast of first signs:
Labour can begin in a few different ways: regular tightening contractions, a low backache or heavy achy feeling, a 'show' of jelly-like mucus, an urge to open your bowels, or your waters breaking.NHS - Signs that labour has begun · pregnancy 28-40 weeks
Reviewed wording: "Labour can begin in a few different ways: regular tightening contractions, a low backache or heavy achy feeling, a 'show' of jelly-like mucus, an urge to open your bowels, or your waters breaking. These signs can arrive in any order, and early labour can take a while to get going. If you think labour may be starting, contact your maternity provider for guidance on what to do next."
Whichever way it starts, notice the pattern in the guidance: every path ends with the same instruction, contact your provider and let them tell you what comes next. You do not have to judge the situation yourself, and you do not have to wait for it to feel dramatic.
When to call
Waters breaking means pick up the phone.

Tonight's small action
Make the number impossible to lose.
Tonight, save your provider's after-hours number in your phone favorites and in your partner's phone too, then write it on a card for the fridge. Three copies, three minutes. If the moment comes at 3:12 in the morning, nobody is searching through old emails for a phone number.
