6 weeks no heartbeat….

AI

Hello. So I had an early pregnancy confirmation at 5 weeks. Got my hcg levels tested. They were going up from the 1000s to 2400. Well this past weekend I had spotting on and off for 4 days. Today monday I am measuring 6 weeks and 4 days… he couldn’t see a heartbeat only a sac… but he said it also didn’t look like a miscarriage was happening. Still, he gave me the miscarriage talk and what to do in case of it. he said he needed more time and that nothing else matters until he sees a heartbeat. I am so scared. I hate the waiting game. Has this happened to you and ended up hearing a heartbeat? I saw a sac but it just looked dark… i didn’t see no shape inside…
