I don't know exactly how you feel but I do understand. My first IVF cycle in January was cancelled due to over-stimulation. I ovulated by day 6. Basically I responded too well to the drugs. I was also crushed and felt the same way.... Am I ever going to have a baby? A few weeks later I talked everything over with my fertility doctor and she did some research and found a better drug protocol for me to try. Again, I was warned that it was no guarantee. We redid our cycle in April with the new drugs and I am now 6w pregnant. I really hope everything works out for you!
Best of luck!
