Muüllerian duct anomalies (MDAs) are congenital defects arising from probable teratogenic assault at 6–22 weeks of gestation.Uterine didelphys arises from complete lack of fusion of Muüllerian ducts, resulting in two entirely separate hemiuteri, cervices and vaginas.The incidence of MDA is <5% and the frequency of uterine didelphys is 1 in 1000–30,000 women and twin pregnancy in uterus didelphys is only 1 in a million. This is a case of a gravida 1 para 0, with uterine didelphys and unilateral renal agenesis diagnosed of single live intrauterine pregnancy in the left half of uterine didelphys who had a spontaneous passage of meaty material from the right hemiuterus which were histopathologically consistent with degenerating products of conception, hence confirming a dicavitary twin pregnancy. Management should be wholistic encompassing preconception, prenatal, intrapartum, and postpartum period as any complications may arise at any point.

Cesarean scar pregnancy is the rarest form of ectopic pregnancy. In the Philippines, little is known about its incidence and occurrence. However, increasing rates has been documented worldwide, closely related to the increasing cesarean section rates. This paper reports two cases of cesarean scar pregnancy who both presented with vaginal bleeding. The first case, a Gravida 6 Para 5 (5005), while the second case, a Gravida 3 Para 2 (2002). Both diagnosed early by ultrasonography but managed differently. The first case, managed by hysterectomy, while the second case, managed conservatively by laparoscopic excision of the cesarean scar pregnancy. This paper intends to raise awareness of the increasing incidence of cesarean scar pregnancy, its pathophysiology, different options in the diagnosis and management. Prevention is the key to decrease the incidence of cesarean scar pregnancy. To achieve this, reducing the cesarean section rate should be the primary goal.
