Okay so I've been having my hcg levels tested every couple of days since Tueaday the 17th when I went to the ER with cramping. They told me I had a threatened miscarriage because they couldn't see anything on the ultrasound and that my levels were only 210. At this point I was 5w2d based on my LMP. I made an appointment with my obgyn the next day (wed) and my levels had risen to 311 but then they only went up to 492 on Friday. I had a repeat test the following Monday which read 974 at 6w1d and they moved up my sono toTuesday  where they found what looked to be a gestational sac and yolk sac with a possible hematoma. Then Wednesday I had more blood drawn, at my local acl this time, and my numbers only came back as 1209...can anyone give me some insight as to what's going on please? I'm terrified of losing my baby but am trying not to dwell on the negative. It seems like I double every three days instead of two so could that be normal or am I earlier in my pregnancy than I thought? I'm scheduled for another sono next Thursday with a doctor visit afterwards to discuss it but I'm worried my stress might hurt the baby.
