Will I miscarry?

Elizabeth
Please help. I had my 7 week viability ultrasound yesterday and baby was only measuring 6w1d and the baby heart rate was about 106 bpm. The RE off the bat told me it doesn't look good, my baby seems like it's off to the side of my uterus too. He said they will monitor me and get me started to try again..I was like wait what I just saw my baby's heartbeat. He had me do a formal ultrasound at radiology, and the u/s technician did the scan for me. He told me, he's not a doctor but it looks like the baby is in a safe place. Later, the nurse called me and explained to me the baby is OK for now. Baby measuring small can be quite common and the baby's heart rate is a little bit slower than they like but the baby is still small so it's not something to be too worried about right now. This is somewhat reassuring but anybody have a similar experience that still have a healthy pregnancy. I already had one miscarriage so hoping so hard that this one makes it.
