The diagnosis can be challenging and often underdiagnosed due to the presence of an intrauterine pregnancy. We aim to present a rare case of HP, characterized by the presence of intrauterine twin implantation. This case highlights the importance of maintaining a high index of suspicion for HP even in the presence of a viable intrauterine twin gestation, particularly following ovulation induction with clomiphene citrate.<\/jats:p>","DOI":"10.1002\/jcu.70216","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T02:54:20Z","timestamp":1773024860000},"page":"1510-1513","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Heterotopic Pregnancy With Intrauterine 7\u2009Weeks Twin Implantation After Clomiphene Citrate Treatment"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2400-0772","authenticated-orcid":false,"given":"S.
