With regards to refusing scans although unwound never do that myself I just remembered some things from my second pregnancy.
The 20 week scan resulted in what was some pretty grim news that pretty much sparked everything that happened in the pregnancy from then on. Due to a ScH I'd been scanned repeatedly in a&e. All of which showed a happy healthy baby at the correct measurements for gestation. Because of has so many scabs in a&e my 20 week scan happened to be at 22 weeks.
This is where it all kicked off.
I Was scanned fortnightly from then on as a result of concerns re growth.
If I'd have had the official 20 week scan at 20 weeks then no one would have been any the wiser. Measurements at midwife appointments didn't spark any concern at all. And all the scans after that showed dd continuing to grow.
I really think that they just happened to scan as she was having a "blip"
But as a result of this blip I was scabbed every two weeks told my baby would he premature and not only that her size would mean she would possibly not tolerate labour. All this was what contributed to me being unable to have a home birth again.
Ironically the last scan I had the computer system at the hospital wasn't working. So results had to be manually drawn up.
Now the midwife appointments would have showed up her transverse position.
I would have been able to have an actual discussion about my options as opposed to it all being pre decided as a result of the scans.
I'd have probabky had a bit more time to decide as well as they wouldn't have been so worried and and if not have been told they'd induce at 38 weeks is have been allowed to go longer if I'd have had a chance to decide whether unwanted the ecv or a section
Ironically the results of the last scan came through when I came home from having her. And surprise surprise they measurements were all back up to where they should be meaning I was pushed into things I probabky didn't need pushing into.
Scans are great in so many ways and provide so much vital information however to many cab be counter productive in that they pick up things that would work themselves out and would never have been discovered at all of not for unfortunate timing.
