I saw your post and HAD to respond. I was pregnant with my DS about 3 yrs ago. I had the same test with the same results and didn't think anything of it early on, but also, couldn't really figure out what it meant. I asked a nurse and her response to me was, "you should try googling it"
 Long story short, I was told time and time again that "this could result in a negative pregnancy outcome." I continued to have a pretty amazing pregnancy, but toward the end, my Dr. kept pressuring me to do all of these ultrasounds and testing, based on these results. I was always reluctant but didn't want to "risk" anything, so I went along with all of it. Everything in the end was absolutely fine, except for the torment that my Dr. put me, my DH and unborn DS through. I am still upset by how many ultrasounds and bad advice I received by my Dr. and midwives. I was later told that they don't really think this is an "issue" anymore and they try not to do as much cautionary testing with it. It has convinced me not to let Dr. get involved if I ever get pregnant again. Sorry, I really needed to vent about that, and of course, I am not an expert, that was just my personal experience, but It really did almost ruin a perfect pregnancy for me, so much worrying over nothing. Good Luck and remember to trust your gut.
