@thefishthatcouldwish that's so brilliant! 🥰❤️the first scan offered at ours would be at over 7 weeks so around the 7-8 week mark depending when the transfer was & availability.
@ChicaXS I totally agree with @UnicornPuff, I'm having private treatment due to a weird situation after our first IVF meant we've now lost our right to half our "only one" Nhs funded round when we were childless as we had to transferred a FET to a surrogate as I was having chemo. It worked, and so now we pay for everything despite only actually getting our embryo creation made on the NHS as a childless couple no transfer or any drugs even despite it being due to chemo. HOWEVER the cost of an FET for us is about £2000 now each time (this is our second this year now) as opposed to the £4000-4500 for the full fresh cycle & my embryos used are from 4 years ago. I'm now older & more hagged.
So if you have the option of a full fresh cycle now on the NHS do it & freeze the embryos, as you shouldn't also pay storage costs for a while (maybe 2 years dependant on your trust) but you also pay for that every year if you have a living child over 6 months.
I don't know about PGS or what mosaic is we've never been offered PGS or paid for it.
