HOUSTON -- Instead of planning for her high school graduation, all of Victoria Calderon’s time senior year was spent getting ready for a baby.

Her pregnancy was a surprise, and her parents were upset.

“At that time, I was like, what am I going to do? Look what I’m doing to my parents. What if they break up because of me,” Calderon recalled.

Victor Michael Calderon was born just a few weeks ago, and his mother’s dreams of going to college have been put on hold.

Student journalist Stephanie Madrid first brought this story to 11 News’ attention.  She told us more than 60 girls at the high school she graduated from were either pregnant or already teenage mothers.

For the first time in 15 years, teen pregnancies are on the rise. Experts aren’t sure why.

Some say it’s because pregnancy is considered cool.

This month, OK Magazine featured a story about 17-year-old Jamie Lynn Spears and her new baby.

On the cover, the teen celebrity declared: “Being a mom is the best feeling in the world.”

Others blame a lack of sex education.

“I don’t think it’s good for anybody to have unprotected sex, to have sex really, but not everybody is going to listen,” Calderon said.

Planned Parenthood said Texas leads all states in unintended pregnancies. Sixty-three out of 1,000 girls become pregnant in Texas between the ages of 15 to 19.

The national average is 43 out of every 1,000, which is a higher rate than many other countries.

“They deserve that information, and we know by looking at other countries and looking at that information, young people with the tools can prevent unintended pregnancies,” Planned Parenthood’s Meryl Cohen said.

And clearly, many teens can’t handle the demands of motherhood.

“I wanted to hurt my baby at that time, I was like, I don’t know what to do,” Calderon said.

She feels differently now, and her parents have come around, too. Calderon said they are very supportive.

Still, nearly every week in this country, police question a teenage mother about the death of her newborn child.

Some, like a young mom in Baytown, are charged with murder. That teen allegedly flushed her baby down a school toilet and stuffed paper in the infant’s mouth to keep it from crying.

As for Victoria Calderon, she’ll soon have some company.  Her twin sister, Virginia, is 5 months pregnant and is living with her parents.

That child’s father is working at a grocery store.

“I am still kind of scared, because I still cry whenever I find out about our bank. We don’t have that much money and stuff like that,” Virginia said.

Both Virginia and Victoria said if they could go back in time, they would not have gotten pregnant.

Because becoming a mother changes lives – a change that’s happening too soon for these twin sisters.
