It's her family affairs and they will solve the way they feel right.  Even Obama came and said this  is off limits. His mother was also pregnant when she was just 18 that also without the wed lock.  It is wrong to judge the person morally especially in this matter when the whole American family is related with this issue one way or around regardless of  races or parties.
Over here if your teenage daughter  or any adult daughter becomes pregnant without wedlock, the family supports  the girl's decision and think it is morally right to do.
