I was medically managed at 16+5 although the baby's measurements were between 12+6 and 14+1.
Initally, i was desperate for an erpc off the bat, insisting I could NOT see the baby. I felt it would smash me into milion pieces when I was already griefstricken t the idea I was carrying my dead baby round.
It turns out that if your uterus is bigger thn about 12 weeks, it's safest to manage medically and I accepted that I'd have to do it even though I didn't want to.
It would have been quite easy to not see him, but in the end, when I delivered, I was overcome with a real need to see him. And he was beautiful. It bought me a peace I could never have imagined to see him and spend a little time just taking him in.
What I'm trying to say is, you're being medically manged for a reason - question what that is. if it really is best physically for you, then you cn get through it without seeing much. You'll be given pns to use over the toilet and it'll be more thn possible to cover it/not look. But conversely, you may feel differently when it truly comes down to it.
Try not to be scared.
(oh, and with regards to the physical pain, my hospital were very on top on managing it - you shouldn't have to suffer too much even if it is just physical
)
