Okay so I've been going through quite a lot the last couple of days and I'd like to know your opinions please. Tuesday evening I went to the ER because I've been having pretty consistent cramping for about a weeks and a half or so. After 5.5 hours I was told they couldn't see anything on the ultrasound and that my hcg levels were 210...so they diagnosed me with a threatened miscarriage. I went to my obgyn the following afternoon and my levels had risen to 311 but they still couldn't see anything on the sono. I got more bloodwork today and another sono next Thursday to see if everything is okay with baby. Does this sound normal at all or am I going to miscarry? This is my second pregnancy and my daughter is so excited to be a big sister...
