Abnormal ultrasound advice!!!

writerkms

Hi ladies!  I am hoping that someone might be able to give me some hope.  I had an abnormal 9 week ultrasound today.  The OB said there is some tissue lying alongside the baby.  She has never seen it before and has no idea what it is and neither did the radiologist.  I am being sent to fetal maternal medicine.  I can't find anything online and I am so scared that this means I will miscarry.  I have had two previous losses.  Thanks for any advice/insight!
