This is going to seem like a silly question but something I have been musing on and wondered if anyone can advise 
I am currently 23 weeks pregnant and have been warned that for various reasons, I am at a higher risk of going in to pre term labour.
So having never had a baby before ... how will I know?!
Midwife told me that at an early gestation, I won't get the "gush" of the waters, if they even do go. I suppose you get contractions still though, but how do you tell the difference between these and say Braxton Hicks?
I should also add, that baby is due to be born via c section for medical reasons and so if I do go into premature labour, I would need to act fairly sharpish to ensure baby is delivery by EMCS and not naturally!
