Ally Opfer didn’t have much time to get used to the fact she was going to be a mother. In fact, she was already in labor when she arrived at the hospital. Though she thought her pain was caused by kidney stones, an ultrasound revealed she was 38-weeks pregnant.

The 23-year-old’s son, Oliver, was delivered soon after by c-section. The Cleveland mother had a healthy boy, despite not following a planned diet and prenatal plan.

“I always loved babies and knew I wanted to be a mom one day,” Opfer told  InsideEdition.com. “Not necessarily right then.”

Opfer shared her emotions after her son was delivered: “I was shocked and didn’t really believe it. I didn’t realize how much I needed him until I had him.”

It’s been a year since Oliver’s birth, and Opfer, along with her family are still baffled by the little guy’s sudden arrival. Opfer explained she’s always had irregular periods. When they abruptly stopped, she took several pregnancy tests, which all came back negative. She didn’t think there was anything amiss.

“I felt fine, I never started showing, everything was normal,” Opfer recalled about her pregnancy.  “It could be because the way I was carrying or the way my son was in my stomach. I’m not really sure why I didn’t show.”

Opfer isn’t a drinker or smoker, though she did consume tuna and deli meats during her pregnancy. Doctors advise avoiding these foods.

“I wasn’t eating healthy either,” she joked.

All teasing aside, Opfer noticed something was wrong when she started experiencing painful menstrual cramps. For two days, the pains continued until she was finally taken to the hospital where doctors discovered she was in labor.

Because of complications during her term, little Oliver was born via c-section the day before Christmas Eve. A year later, and he’s doing fantastic.

“Even though I didn’t think I wanted a child or needed one yet, once he came, he definitely made me realize how much I needed him,” Opfer said.

“He is my very best friend,” she said. “Our connection is so strong. He is always following me around the house. We are always playing together when I am home.”

Surprises, though not anticipated, can bring joy when we least expect it. For Opfer, she received the precious gift of her son. Oliver’s added light and love and happiness to her life, and that is invaluable.
