Why does my grandma do this?

My grandma is 89. I understand at her age I need to have a lot of patience, which I feel I do. But now that I’m pregnant my patience is running superrr short.

She doesn’t know I’m pregnant yet, and she constantly asks me if I use birth control (she’s VERY against it) and I’ve told her no I don’t. She asks me every so often cause she knows I’ve experienced a miscarriage and she’s even referenced me having an abortion which I DIDNT and which she’s also against. She asks me these things once a week, and I hate that she thinks I would even be capable of doing those things and she thinks I did something to cause my miscarriage and she told me those things don’t happen on their own. 🫩 it’s exhausting having to explain myself over and over again over something so delicate to me.
