Good day everyone! Yesterday I had a 3rd ultrasound, they said my uterus was in strong tone and also slightly inflamed placenta, and the baby's head is close to the entrance of the small pelvis. When I asked "what should I do", the sonographer said to wait for the doctor's appointment or call an ambulance if it gets worse. Now it's 31 weeks and 2 days, I got sick again, sore throat and runny nose. Can you advise, maybe it's better to go to the hospital myself? I am very worried about the little one.
