What is the book where 3 girls get pregnant and plan to raise the children together?

"After one month of trying I became pregnant and had a beautiful healthy boy!"

"After over 7 years of trying to conceive and thousands of dollars spent on infertility treatments, I had actually succeeded to get pregnant the natural way without any drugs or medical intervention "

" I just wanted to say thank you for writing this program and for giving hope to women at my age. I am 46 and I am finally going to be a mother."

I only read the beginning. I remember that there was one girl who had gotten pregnant and and 2 best friends decided to get pregnant too and raise all the kids together. I think they were seniors and all good students and and had a future but turned it down to have the kids.

It was based off the pregnancy pact thing at the high school in Maryland.
