Sac but no baby

E

I went to a clinic at 5 weeks 6 days and a fetal was found inside the sac with a flickering heart and at 6 weeks 5 days no fetal was found at a different clinic .

3 days ago I began to spot at 8 weeks 1 day and it got darker the next two days all

I went to ER and they think I’m miscasting but my hormone level is at 21000 so I have to go tomorrow to do another hormone test . If it goes down I misscarried but if it goes up then they have to see where the baby is growing.

They don’t think I’m having an ectopic pregnancy because I am not in pain.

Is anyone else going through this ?
