Caution the babies in my dreams are sometimes not quite real or I forget about them, or in the last dream it fell out of the sling when I lent over to pick something up 
Kwick when I dream about sex it's often my ex who I didn't even want to have sex with, which means I wake up annoyed!!
Cazinge the egg collection isn't that bad. Plan on resting afterwards and have some pain killers and a hot water bottle handy.
Dream I phoned LWC because I find sorting appointments out over email a pain.
Re South Africa, not heard that mentioned on here but their currency has just dropped even lower so could be a good deal! Bear in mind you'd need to be out there for a while if that clinic was doing the scans to check follicle growth too, booking a last minute flight would be expensive, your frozen embryos would be over there so you'd have to go back there for a second which might be harder with a kid in tow. You'd also need to look into how the rules about donor anonymity etc apply.
I think the thing about your age is silly, it's not like you can't meet someone later or eve go on to have kids with someone else. What happened to Mr Right? Read the Atlantic link if you haven't already, it. Igbo help with the age worries.
You are young enough to do egg share but it will also depend on the results of the tests they do.
