At the beginning of the movie, Ashley Judd's character is taking an ovulation test because she and her husband are trying to conceive a baby. Later, this theme is reinforced when Morgan Freeman's character offers her a drink and she declines, saying "I'm trying to get pregnant." Shortly thereafter, the two are in a car accident and a hospital nurse later tells her that she lost her baby. But in order for a miscarriage to have been noticed at the hospital Ashley would have had to be at least a couple of months along in her pregnancy - and surely any woman trying so desperately to get pregnant would have noticed a couple of missed periods and even more likely would have been taking pregnancy tests all along. [during the first trimester some women get what is known as spotting - like a false period. Also although pregnancy tests are usually accurate, they aren't always and it can take a couple of months before they accurately tell you whats up. These two things are both linked to high stress - something which she definitely was in.]
