I am being asked by my doctor to take betnesol injection two shots beginning tomorrow. I am 30 weeks pregnant and my fetus weight is around 1744gms. AFI is 11.3. According to ultrasound report the head circumstance is 95 percentile . I am on the border line of sugar, BP 130/140 n thyroid. As per my findings if I take this injection I might get into preterm labor and might have a premature baby. What should I do as I am really worried and do not wish to have a premature baby.
