A diagnosis of an early ectopic pregnancy was made. The patient received an appropriate dosage of methotrexate IM and was advised to return on days four and seven after the injection for repeat levels of b-HCG to be drawn. When she returns on days four and seven, the b-HCG levels are l,900 mlU/ml. and 1,000 mIU/mL, respectively. Her bleeding and abdominal pain has resolved by day seven. She is then scheduled to return weekly for repeat b-HCG levels.
