Hello everyone) My aunt had a frozen pregnancy last year, the baby died at week 16 (I think). A year later she got pregnant again, she prayed with her husband for a child, today she had her second ultrasound, everything is good with the baby, but she's having an opening and cloudy water, they said they will have to call for another delivery, there's no chance, why does this keep happening? ? Has anyone experienced something similar? After all, the baby is in order, everything is fine with him, she feels his movements, such little ones sometimes get taken care of?
