Ivf bad result

We were hoping to have another brother or sister for my 10 month and fell pregnant 3 months ago.i was told I couldn't keep baby as the beast cancer I'd been diagnosed with 1 week later was a Grade 3. I had to stop breastfeeding. Grief. Abort wanted child. Further grief. Then go through ivf. On the morning of the chemo I got a call. My follicles had been plenty. 14 in each ovary. But only 1 egg was good enough! The call was to tell me the egg had seized. So all hope had gone. Further grief but no time to compute as was having canola threaded in to me 2 hrs later. I feel numb so far. Like I just exist. I want to be positive. Day two after chemo and I feel like I'm just waiting for the next grief/horror. Has anyone else lost the ivf challenge?  I mean I'm clearly fertile but on that cycle it just had enough my body probably didn't know what was happening. One day baby next day gone two days later new stimulation. It's been very hard.
