Faith- I also agreed with the sisters, see the Drs 1st. Then maybe ask them how the system work, then decide which one u are comfortable with.
I'm with Prof Wong. Though he is quiet & bzy man, he will sure answer all yr queries. But is better to write & prepare all yr qs. Scans are all done by him. Chr nurses are very professional & I personally felt that the overall feeling & support from them are good.
Even after ET, during 2ww, any queries or if any spotting issues, they will advise accordingly
