about a week or two after finding out that i had that and my ob just had be go in every two weeks and baby is fine i still has a little bit of blood when I was like 16 weeks but it cleared up and baby is fine.
Mine is 3cm, I had an US a few days ago and it did shrink a little, I go back at 12 weeks to get checked again, it is stressful! They told me if could detach my placenta, that's what scares me the most
