Astrology Question Regarding Predictions on your chart?

This is a serious question. I want to know if anyone found their astrology charts to be accurate. I have a barren sign in my fifth house. Which afflicts infertility. Would this explain 8 years of no pregnancy. This year I am trying....I was told it would be difficult getting pregnant and holding it to term. Have anyone ever went through this and the opposite has occured. There were fertile signs in my chart, but its more negative then positive there. Please share your thoughts and serious ones plz. Thank you.
