A woman from Texas got the surprise of her life when she learned she was pregnant with triplets, but she was simply in shock after her first ultrasound.

Silvia and her husband Roel learned that she was carrying two, tiny conjoined twins plus a third sister who was separate from the other two.

This anomaly occurs only once in 50 million pregnancies and the courageous mother gave birth to the three girls in perfect health on the 34th week of her pregnancy.

The two conjoined twins, Ximena and Scarlett, are in perfect health and an operation to separate them is scheduled for January 2016.

We wish the best of luck to the little family, here are some pictures of the girls.
