Hello my name is shelbe, I am 40 and have just started the stims for ivf #2. Yesterday at my first bw/us check up the DR noticed 1 leftover follicule. She did not seem to be concerned. Have you ever heard of such a thing and is this common? Why would there be a follicule left after ER? I would appreciate any advise or comments on this you would be able to offer. Thanks. Shelbe
