Jana Kramer revealed that she was hospitalized for a kidney infection during her babymoon with fiancé Allan Russell.“Well. Our babymoon didn’t go as planned but there were some lessons learned. First off and most important, baby is good♥️,” the “One Tree Hill” star captioned an Instagram carousel of hospital photos Sunday.Kramer revealed that she was admitted for a “bad bacterial infection that got into the kidneys.”The two-day hospitalization came after the country singer, 39, had repeatedly “brush[ed] off” back pain she had been feeling “for weeks.” “Lesson number one…don’t just brush off pain, because it can be more serious than u think,” she wrote, adding that moms often ignore warning signs because “we are the last ones to take care of ourselves.”She continued, “When I posted about my back hurting a week ago I just had chalked it up to pregnancy and didn’t tell the doctors because back pain is ‘normal’ so ‘don’t be a wimp’ is what I thought.”However, Kramer recalled that she reached her breaking point when she and Russell traveled to Florida to celebrate the upcoming birth of their baby. “When we landed I just couldn’t handle the pain anymore and I started to feel even more sick so we went to the hospital,” she wrote.
