Welcome Rachel there is a wealth of knowledge here on SA but like Em said most seem to go to CFC (cape fertility Clinic) in Cape Town.
We are about to go over in March and our dealings with them so far have been very professional. The only frustrating thing sometimes is the time difference ....
As far as timing goes the 'official ' line Is 12 days. So for us we have to be in Cape Town for our first appointment on 24th March, EPU is likely to be the 26th. ET likely to be 31st and fly out day the 4th.
(To all the other ladies , yay! We finally got our treatment plan exactly a week after all the testing)
You basically fly out before you POAS or BT so yes if you do get a bFN it means another trip.
Lily : Big hugs to you , that is something I worry about too. I hope the search for a new donor isn't too drawn out.
My heart - I would be going with your gut feeling....
Em: good luck for your donor's testing today. Fx.
As for us , we are all systems go .. I have started my meds. The donor has picked up hers, flights are booked, accommodation paid for and now our time can be spent fussing over the fun things like shark dives and safaris
