Dee - When i was pregnant with Lily she engaged at only 28 weeks and stayed there until she was born, she never disengaged. Yet i had to be induced 1 week over. She was fully engaged for 3 weeks before she was born(ouch!) So that really is no indication bub will come early at all. I was also getting a lot of braxton hicks, some lasting for 3 or more hours at a time and were close in intensity as actual labour was. So I wouldn't worry. Bub will come when s/he is ready to!
