When exactly does labour pain begin?
An exact answer cannot be given as it varies from woman to woman. Some feel pain before going into labour. Others feel it only after being in labour for some time. Just remember that whenever your pain starts, inform the doctor immediately.
Tummy aching is a sign of labour, isn't it?
Not always. There must be changes in the cervix for labour to have started. However, if you are feeling the pain, let your doctor know.
How will I manage pain that occurs before I reach the hospital?
This is the reason childbirth classes are recommended. Most classes teach you relaxation and breathing techniques that help in managing contractions smoothly and, as a consequence, ease labour pain.
