I had a v similar statement given to me at 39 + 2. They wanted to induce and I begged for a half measure (sweep) first. When I went back 1 1/2 days later I had another. Was only 1 cm, but 5 hours later had baby! Don't be disheartened, do go back for another. Second / third sweeps are often more effective.
I know it'll happen when it happens but I like to know that it could happen imminently and that keeps me going. Being told nothing's going to happen in the next few days is deflating and ain't going to do much for old oxytocin levels
