I had contractions at 27 weeks with my second baby and went on to have her at 37 weeks,and with my third baby i had contrax at about 28 weeks,and had her about 33-34 weeks...
With Dominic i had a few pains at about 30 weeks,but my waters didnt break until i was 36 weeks...
I hope everything goes well for you,im sure that bub and you will be just fine...
