Can you even get pregnant safely wearing a corset all the time? (⊙…⊙ )

They had pregnant corsets! Also remember corsets weren't actually bad for you and we're like the bras we have now! Support! Posture! The only time it was bad like the way your thinking is the rare case of tight lacing

historically speaking few corsets were the type we think about today, those existed only for a short period, there's some videos on YouTube I think. And even then they were changed over for very short corsets that stopped under the bust when the women were pregnant, their version of a bandeau bra in some ways.
