I’m trying to not stress and worry but it’s so hard . My last US as at 6w 4 days baby measured right on track with a heartbeat of 115 but my gestational sac is measuring behind . At this point it can go 50/50 and I’m terrified I started having some light cramping but no spotting or anything still have symptoms I’m just so scared all of the time that I’m going to loose this one too. I go back the 31st for a repeat US to see if the sac has grown any because if it hasn’t the baby will run out of room to develop … I’m just a mess of nerves
