Bbhope....The long down regulation takes about 2 weeks, so then your stimming isn't synched with the start of AF, like other protocols are. That's how the clinic can give you the date of Dec 13. I never quite worked out why the other protocols work off the menstrual cycle, but the long down one doesn't, but it seems to work. That's great that you have a date locked in. Did you say the Dr G will now organise a FS for you through IVFA, or have you already got that sorted yourself?
AFM.... my cycle was cancelled today when it seems that I've ovulated my big follicle early!!
