Girls, hello! Could anyone tell me if they've had this experience? Today I had an ultrasound at 27 weeks (I'm looking at the cervix in real-time because it's short). My sonographer said there is early placental aging of 1st degree. How dangerous is that? Has anyone experienced this before, what did they take, and how did they do? Thanks in advance.
