Previous gestational diabetes, GTT results...

In my previous pregnancies I have had diabetes, I am so used to having scans to monitor babies size and being induced at 38weeks.  Well I'm 29 weeks tomorrow and I've not got gestational diabetes. I'm over the moon and feel a million times healthier than I have in any of my previous pregnancies. All that aside I'm now really scared of going into labour on my own, everyone seems to assume it's all worked out because it's not my first baby but I actually have no idea if I can even go Into labour myself or what it feels like! I've also heard that the drip I've always had makes contractions more intense, what if I don't realise. Funny how no matter how healthy you are there is always something to worry about. Any other ladies had similar experiences?
