Did anyone have a miscarriage from this due to a large clot? I lost a baby at 14 weeks in May due to a large clot in the placenta, and my doctors weren't sure if it was because of this, or if I had Hughes syndrome. Now im pregnant again, and I'm honestly freaking out. I'm so afraid of losing a third child, i just feel like crying all the time.
