A nightmare

Elissa
I had my Anatomy Scan today at 19w1d and they said baby is growing just fine according to my due date. Then they found that my placenta has been bleeding. Tech had been asking if i have bled during this pregnancy and i haven't at all. Dr came in and said i have to come back in 5 to 6 weeks to check if it has gone away if not they will take it from there. She also said it sometimes clears on it's own but if it doesn't it will cause the baby to stop growing and we all know what that means 😥 I am just so scared to lose my baby. Has anybody gone through this or is going through this right now?
