My gf just recently gave birth and she was early and told me that she didn't know she is contracting as the pain was in her upper tighs and no pain in her back or belly!!! She got to hospital late as she didn't recognize the pain. Eversince I am confused as I always thought contractions are period like pain intervals. Could those of you, who have been through this explain to me how your contractions were and what they were like? How did you know you are contracting?
