When the post-fertilization age was unknown, then the physician's estimate of gestation was used. There were 7 terminations where the gestational age was not reported.
An estimated gestational time was calculated for 3 of the 7 terminations without a reported gestational age or post-fertilization age.
The date of the last menses and date of termination were used to calculate the estimated gestational age: 1 (33.3%) occurred at less than 6 weeks; 2 (67.7%) occurred at 6 to 8 weeks.
For the remaining 4 terminations, the date of the last menses was unknown.
