Dryness after vacuum aspiration

S

I’m a female who has always gotten super wet when turned on. I never understood why lubricant was even a thing. Last year I had a miscarriage which the doctor then did a vacuum aspiration for. Since then, I’m so dry, it’s like I can no longer create wetness myself. Is this a normal side effect? Any idea for what has caused the change?? This is 6 months later... still just dry.
