I've been on gonal F for the last 2 weeks and buserelin for around a month. I went for my 3rd scans today and they could only see 4 eggs and a few small ones but none of which are ready mor matured to be collected. The nurses are adamant that I must go for another scan on Monday and a the collection will be Wed/Thurs. I feel they are jumping the gun and assuming my eggs will be fully matured and ready by Wed. Can they proceed to collect the egg(s) even if it's not ready?? They are just worried that continuing my injections will create over stimulation but I'm just injecting once every 2 days anyway, so no risk to that and I've had no adverse reaction to any of the meds.
