A systematic review and meta-analysis in 2012 [16] concluded that there is insufficient evidence to establish a difference between metformin and clomiphene citrate in terms of ovulation, pregnancy, live birth, miscarriage, and multiple pregnancy rates in women with PCOS and a BMI less than 32 kg/m 2.

Spontaneous fetal termination after 20 weeks of gestation is known as a stillbirth. [15] The term miscarriage is sometimes used to refer to all forms of pregnancy loss and pregnancy with abortive outcomes before 20 weeks of gestation. The most common symptom of a miscarriage is vaginal bleeding, with or without pain. [1]
After ovulation, the follicle remnant is transformed into a progesterone-producing corpus luteum, which shrinks and disappears after approximately 12–14 days. In PCOS, there is a so-called "follicular arrest"; i.e., several follicles develop to a size of 5–7 mm, but not further. No single follicle reaches the preovulatory size (16 mm or more).
Others have defined the condition as blood loss of greater than 1000 mL after either delivery method, or any amount of blood loss with signs and symptoms of hypovolemia. [7] Secondary postpartum bleeding is that which occurs after the 24 hours up to 12 weeks after childbirth. [7]
Bleeding before childbirth is that which occurs after 24 weeks of pregnancy. [4] Bleeding may be vaginal or less commonly into the abdominal cavity. Bleeding which occurs before 24 weeks is known as early pregnancy bleeding. Causes of bleeding before and during childbirth include cervicitis, placenta previa, placental abruption and uterine rupture.

Transvaginal ultrasonography showing a gestational sac with a diameter of 28 mm, corresponding to a gestational age of approximately 7 weeks and 5 days.
