Not quite as out there, but as soon as someone mentions having scans, I immediately think of dildo cam and wonder why they have instructions to have a full bladder. BW
Oooh yes, this is me!!!
I say ''an internal scan?'' and they say ''huh?''

I do it a lot when people mention blood tests etc as well... and I find myself looking at things like follicles, etc in articles & then confusing myself if not reading it properly

I do find myself saying things to ''normal'' people as well (with reference to IVF things) & I forget that they don't know what I'm talking about when they look at me blankly (especially the abbreviation FS - I forget that the average person doesn't have one of those )

And you can get pregnant by having sex??!!!! Who'd have thought?!!!
