So when I first got an ultrasound done at 7 weeks there was an extra sack but only one baby and then ended up going to the hospital at 12 weeks because I was bleeding a lot of bright red blood and they think it’s bleeding from the other sack that was empty but the doctor still saying that it was a threatened miscarriage. Should I be worried? Because all’s I’m scared about is losing my baby and it terrifies me now I am 13 weeks and the baby has a strong heart beat and moves around a lot plus my cervix is closed but still have some blood loss. Any thoughts on what to think?
