Had my 3rd ultrasound today. My first ultrasound showed nothing. I went to my second ultrasound thinking I was 6 weeks, we only saw the amniotic sac and they told me I was 5 weeks. Wasn’t given a due date or any further information. Had another ultrasound done today, should be roughly 7 weeks and saw the amniotic sac and yolk sac but no baby and no heartbeat. I asked if that was normal and was given no answer. I feel so frustrated and worried. Has anyone had a similar situation?
