I don't think she's unhealthy (and is probably healthier than me, lol) but she has been trying to have a baby for 6 years and can't get pregnant. She actually started doing fertility treatments this past year and it still hasn't worked.
My grandmother is
convinced that the way she eats is the cause, but she doesn't have the balls to say it to her.
Instead, she just frets, worries and shakes her head whenever the subject comes up.
