Hi Miracle_Happens, I think you are the same as me, process was prolonged. If my understanding is correct, the process requires 6-8 weeks. I was told mine was about 6 weeks protocol but when collecting my Lucrin, they have prolonged to 8 weeks as Nov is very tight for them.
As for the scan, depend on the result for the egg & lining (if I'm not wrong), for me, usually more than 3 times.
