No Fetal HB at 13 week appointment

Krystal

I went to my 13 week appointment and the medical student that was tagging along tried to find the babys heartbeat for about 3 minutes. The Midwife came over and tried for another 3 minutes and could not find it. They said they wanted to get me in for an ultrasound today but along with the spotting I have had on and off it can be a sign of miscarriage!? Im freaking out, currently waiting for my ultrasound! Has this happened to anyone??
