I went into labor and delivery because i had been having a slight trickle of fluid for a week. I went in and got swabbed and it was sent off to the lab. The test came back negative for amniotic fluid. But my doctor ordered a fetal fibrobectin test after that, that test came back positive.. My cervix length is fine, my cervix is closed and i had no.contractions in the 6 hours i spent in labor and delivery. The nurse.said my doctor ordered 12 mg of betamethosone that day and the next and then i'd come back for another.course in a few weeks. i can never get my doctor on the phone so i have really had no explanation of whats going on, i am 32 weeks and never thought i would go through a pre term labor scare like this and i am truly in the dark. I have never had a preterm baby i always carry to term or within a few days.. can this injection cause harm if it is not needed?
