I think it will be different for everyone. My friend was in a similar situation and went into labour after almost two days.
I think you can try timing your contractions. Here are some characteristics of labour contractions:
- Contractions come at regular intervals, gradually getting closer and closer
- Each contraction lasts about half a minute to over a minute
- Contractions get stronger over time
- Contractions persist despite lying down or resting
- You can feel the contractions in other parts of your body like the back
- You have contractions and your water has broken
As a guide, if you experience regular contractions every 10 mins or less, it is time to head to the hospital as you are likely going into labour.
