A Massachusetts woman was surprised to found out she was pregnant, just about an hour before giving birth to a healthy baby girl.

Judy Brown, 47, went to Beverly Hospital in Beverly, Massachusetts on Wednesday with severe abdominal pain. To her surprise, Brown’s health providers discovered that she was pregnant and in labor. Around an hour later, Brown gave birth to a healthy 8lb baby. She and her husband of 22 years named her Carolyn Rose, ABC News reports.

Brown told ABC News, “It was a little bit scary getting into the hospital thinking something was really bad was going on. To understand and take in that was I pregnant and was about to go into labor … it was very overwhelming.”

Dr. Kimberly Gecsi, an obstetrician and gynecologist at University Hospitals Case Medical Center in Cleveland told ABC News that it is possible for women to not realize they are pregnant until close to giving birth. “People don’t know sometimes or they’re in denial about it and denial can be pretty strong,” she said.

Women in their 40s can still get pregnant if they have not gone through menopause. The Office of Women’s Health at the U.S. Department of Health and Human Services says if women are still having periods, even if they are not regular, they can get pregnant. Even though her body had been undergoing changes, ABC reports that Brown did not consider she might be pregnant, due to her age.
