i have been searching for anyone who has experianced what i just went though. i went through all the shots for ivf-2nd time, (first cycle cancelled due to poor response), took my hcg test, went in for the retrival only to wake up and be told they found no eggs and no hcg was found in my system. i am a wreck in thinking i did not give myself the hcg shot correctly. My doctor mentioned taking Ovidrel which is a pre filled syringe (would have loved to have known this before!) is it effective? to go through all of this and to fail because of something i may have done is heartbreaking. i prepared myself for anything but not this outcome. it feels like a loss and i am grieving. i hope my story helps someone else; be assertive and don't be hesitant to ask and reask questions.
