Am after some advice and to find others who might have experienced similar: I was due to start cycle 1 of a short protocol for ICSI which has just been cancelled. I took 10 days norethisterone last month, had withdrawal AF, and then an ultrasound on day 2 which showed endometrium 8mm (ovaries were ok with small follicles only), and so the ultrasound was repeated at day 4 and endometrium was 6mm. Target was less than 5mm. They did some hormone tests and then phoned me to cancel this cycle (I don't know what the hormone results actually showed but the nurse implied it was because endometrium too thick rather than the blood results themselves). I know it's good that they cancelled now if they thought it was either too dangerous or not likely to work this month, but I was so psychologically prepared to start and had reorganised life for the scans, EC etc, and can't quite believe it has been halted before we even start. I've read plenty on EC failure, fertilisation failure and implantation failure, but i hadn't even considered that I could also fail to even start the injections....!
I wondered if anyone could tell me more about why the endometrium needs to be thin to start with, if this is likely to happen again and what it means if it does happen again. I've emailed the nurses at my clinic yesterday but still waiting to hear back from them. Thank you all.
