These signs may indicate that you are about to go into labour. However, there is also a chance that everything will stop and you may carry on being pregnant for a while longer.
It is important not to get exhausted in the early part of labour so rest is very important. If you are getting period-like pains, have a warm bath and go to bed for a few hours. Even if you cannot sleep, just relaxing and listening to some music may help you later on.
