My ovaries are premature, is there a chance i'm pregnant?

Premature?: Do you mean your doctor told you your ovaries were in premature menopause? At 45, that would be early, but not unheard of. If a woman has premature menopause, then she won't likely get pregnant, but it would still be possible for her to have a random ovulation. At 45, chances are very very slim to begin with, so we are talking about a very narrow chance of pregnancy.
