Hi, I'm 8 weeks, 1 day pregnant and very sure of that since I went through fertility treatment and IUI to conceive. So basically, there's no room for a miscalculation of my LMP or conception. I had a sono at 6 weeks 5 days and it showed no heart beat with a size corresponding to 6 weeks 1 day. I went back for another sono at 7 weeks 5 days and there was a heart beat but only 104 bpm and the size corresponded to 6 weeks 5 days. I should also mention that i have a very healthy diet, dont smoke or drink, ive taken my prenatal vitamins and am in very good shape. The doctors that are. treating me are saying very little, I literally was only told let's wait one more week to see what happens. Not receiving any explanations from my doctors, I went online to research and have read about IUGR and this potentially being a sign of placenta problems or other very troublesome complications...signs of an unhealthy baby. Should I be worried? What could be happening? Any recommendations ?
