Final answer:
Bleeding does not occur in 100% of ectopic pregnancies, so the answer to the question is that it happens in less than 100% of cases.
Step-by-step explanation:
In cases of ectopic pregnancy, bleeding occurs in different percentages based on various factors. While a definitive percentage is difficult to pinpoint due to these variances, many medical resources suggest that bleeding, often referred to as vaginal bleeding, is a common symptom in ectopic pregnancies, but it does not occur in 100% of cases. Therefore, the correct answer to the question ‘In what percent of ectopic pregnancy will bleeding occur?’ is option b) less than 100 percent as not all ectopic pregnancies result in bleeding.
