Don’t know what to do

Went for a scan today she said she can’t see any sac or baby but then again can be early 3-5 weeks which they can’t see in a scan

Also bleeding .. took bloods waiting to see the hcg level

Or can be chemical pregnancy 😭😭😭

Anyone had this and found out they still pregnant after

My left is aching , is tender 😭😭got all symptoms of it too
