Hello, here's a little story. Maybe someone had something like this before at 21 weeks everything was good, went for an ultrasound and it showed oligohydramnios and only one arterial umbilical cord, they put in FPN 1A, every month I had an ultrasound, I gave blood tests and took vitamins, everything was fine, the baby was well-fed, he gained weight well, at 36 weeks they put in FPN 1B The baby weighs 2300 grams. Oligohydramnios is present but the water doesn't go away, first pregnancy I'm very worried, tell me please ?❤️
