RE smears @MercyBooth - similar experience; not childbirth but I had to undergo tests in hospital in August that involved two catheters into my bladder, another into vagina another into rectum - bladder filled up to maximum capacity (so in severe pain by this point) and then had to pee with catheters in place with three nurses watching (urodynamics) . Which erm, involved straining to go as I couldn’t relax ... in the end took thirty minutes ...
All with a surgical mask on — and no bloody curtain or blanket either, because of covid, thankfully in an empty ward as anyone could have walked past - as it was the cleaner did twice - they said couldn’t have a curtain as ward needed to be well ventilated .
Ended up passing out onto the floor and at that point the nurses said I could take the mask off to get a breath - bit late by then ... absolutely awful . I’m still not sure why I couldn’t just do a PCR and isolate at home first - in the end one of the nurses gave me a hug in the toilet after so she can’t have been that concerned !
I can’t even imagine trying to birth a human with a mask on; it must be absolutely horrendous
