Dear Abby: I'm in my early 20s, happily married and financially secure. My husband and I have been discussing having children. My problem is my sister has been trying to start a family for three years, to no avail because she has infertility issues.

These issues run in our family, and there is a 75 percent chance that I will have the same problem. Should I talk to my sister about my trying to get pregnant, or wait until I'm pregnant and break the news to her then? Since I may have the same problem she's having, I don't want to discuss something with her that may never happen. Any thoughts? – Don't Want To Hurt Her

Dear Don't Want To Hurt Her: "Springing" news that you are pregnant would be more of a jolt to her than hearing that you're trying. I see no reason to keep this a secret from your sister. Because problems conceiving run in your family, talking about it might be helpful to both of you. If you do become pregnant, she may want to consult your doctor. If it doesn't happen, the two of you can emotionally support each other.
