I am 16 weeks pregnant with twins. I was told by my OB that I had complete placenta previa. At 14 wks, Baby #1 measured right around 13-14 wks, but Baby #2 was measuring only 4-6 wks. Both had strong heartbeats, but I was told that Baby #2 may not make it. If I miscarry Baby #2, does this mean that I will lose both?
