So, my older sister, age 30, has been trying to get pregnant with her husband for well over a year now with no luck.

My younger sister, age 18, who is just finishing high school, informed me today that "there's a 70% chance that I might be pregnant" and "my boyfriend and I decided to keep it if I am." Of course, this would have been accidental... at least I think it would have been.

We're not telling anyone else in the family at this point. My parents wanted to send her off to technical college, so they won't be too thrilled about it, and my older sister would be annoyed with her AND jealous.
