I have been on Estrodial and dont remember having that much pain - a little uncomfortable but completely different to a full stim - and like you I have had over 50 follies before and that was a LOT more painful.... I dont want to concern you, of course, but I would consider just giving the clinic a quick call when you can, to see what they say... Although I am sure it will all be just fine.... let us know how you go.

Oh and BTW HAPPY BIRTHDAY MISS ANN!
