i swear what you're describing sounds SO familiar, but honestly, i don't actually know if i read it. so i'm just dropping links to manhwas that MIGHT be what you're looking for, but i actually don't remember if it's any of them since they all blurred together LOL.

I read it around 2018-2019ish Chinese manhua involving rebirth, I don't remember the art, but the mc is a doctor in modern times and she died and was reborn to historical china, the ml has a mask with a condition that no doctor can heal it.
Also I'm not sure if this is from the same manhua but I remember the MC's half-sister getting pregnant and asking the mc to abort it.
