Unplanned pregnancy can happen to anyone including teenagers, young adults, middle age adults, and yes, even during late adulthood. The BIG question is, what happens next. Do you marry this person because you are about to have a child together, even if you don't love them?
Not to discuss politics or anything, but lets look at 17-year-old Bristol Palin and 18-year-old Levi Johnston for example. The heat is on for them and they are the center of attention. One false move and things can go crazy. Are they really marrying for love or is it because she is pregnant, and the world is watching? Will they be divorced by age 25? Do other people think like that: "Oh my God! I'm 27, pregnant and not married! He just HAVE to marry me. What will people think?"
Personally, I don't believe any one should be forced to do anything, man or woman. Marriage because of pregnancy may have been wonderful during the 50s, 60s, and 70s, but times have and are changing. People's morals and values are different now. Not all young adults are family oriented. So, you marry this person because you're having a child together, but truth be told, you never saw yourself being with this person long term anyway and now you're stuck in a relationship with this person for at least 18 years. Is that how that works? OR, could you compromise on how you're going to raise this child as a team and later decide if you want to spend the rest of your lives together.
My belief is to not worry what others think. I know sometimes that's easier said than done, but it's your life and if you believe in this, you will only have to answer to one-and that's God!

P.S.: No, I'm not pregnant!
