The 35-year-old country singer and former "American Idol" champion told "CBS Sunday Morning " she got pregnant in early 2017 and it "didn't work out." She had a second miscarriage later that year and a third in 2018.
Underwood says she was afraid to be angry because she has an incredible husband, hockey player Mike Fisher, and an incredible son, 3-year-old Isaiah.
She says she got mad when she thought she might be suffering a fourth miscarriage and she "told God how I felt." She went to the doctor and was told everything was fine.
