Hi, I am at 16 week pregnant with twins and having one baby low lying placenta. Suddenly I bleed with no abdominal? pain or no cramps bt it is fresh red blood but not clotting yesterday in evening. I take sustain aqua 25 injection immediately and bleeding is stop. Today morning I have done normal usg for check baby. Both babies are fine. Bt there is show one baby retroplacenta hemorrhage heterochoic area 2.78* 1.15 cm. I take 5 days susten aqua 25 mg or daily one susten 400 mg. I am very scared. This is my first pregnancy. Is it treated by medicines or there is any risk? What should I take precautions.
