Anyone have a chemical pregnancy they can walk me through?

Kris

I thought I had my period last Monday and had a positive test the Wednesday... had my levels checked and Thursday hcg was 139... yesterday they were 152. Only being 4-5 weeks along nothing showed on ultrasound which leads me to believe this was chemical?

Is there a timeline how this goes? Should there be a lot of bleeding ? Can we start trying again soon?
