On the second ultrasound, we saw the placenta in front of one fetus (I have twins, di-di). The due date is 20 weeks and 2 days. Girls, can you tell me if it's possible that the placenta rose? What did you do, how were you treated? To the doctor only on the 30th... She wrote me a physical rest for the genitals, to wear a bandage and no vaginal examinations.
