Hun don't worry!! If he is coming fast your Mid will be there in 2 minutes!!! whereas if it was me I would be waiting about 15 minutes for her to arrive You have felt contractions before, you will recognise them. If you are worried about the boys being there then call me!!! I can pick them up and or keep them distracted for you. Chances are he might be a slightly longer labour than you expect because you will be doing it without the augmentation, so I really think you will be fine.
