My wife is 16th week
pregnant with twins via IVF (own Sperm & fresh eggs). The embryo transfer date is 26th Jan 2020 which is a 3rd day transfer.
We did a NT scan on 7th April 2020(13th week). We missed our double marker test, and now we have to do quadruple marker test. Because of this covid situation we are not able to get in touch with our doctor and it's becoming hard to co-ordinate between lab and our doctor.
We want to do quadruple marker test. So which scan required for quadruple marker test (routine, NT or any other)?
