Hi Jenny, bless you this is such a journey. Immunology is a minefield, that said its amazing how quick you pick things up

Not sure I can advise as on this train and still learning. We had 2 x failed ICSI and failed thaw at FET. Given the demands this puts on us we got level 1 bloods done on NHS.
We then made appt with Dr G and he gave options but really did mean level 2 bloods. Get saving as all quite pricey!
From these you get a better idea of scenarios.
Thinking perhaps if ur thinking along these lines get level 1 done free if u can on NHS and perhaps have ur clinic do an AMH test too.
Go armed with results if need be to DR G and either mail him results and telephone consultation or visit him perhaps!
I'm not much help but could leave you unanswered

Good luck xxx
