Sorry can't really help you with the legal issues, but I'm also with discovery and my entire savings account was depleted with all the blood tests. I was considering going the same route as you but got a bit worried that if I fall pregnant the medical aid must not refuse to pay for certain things because I had fertility treatments. I don't have any information on that. I was just being cautious. Anyway just wanted to ask you if applied for the PMB before you took the tests?
