I just got my first keeper today and i have been reading about the possible accidental expulsion of an i.u.d. I understand the breaking the suction thing. I haven't tried it yet. I am a little worried about if that will be difficult to do if I am a large woman. I mean I can get my fingers in there to check the strings and other fascinating things, but i tried a diaphram and was never really good with it. is that at all similar? Are there any women out there on the bigger of the big side that have experience with the i.u.d. and keeper working their magic together?
