Miscarriage or Chemical?

Sadie

How do you know if you’ve had a miscarriage or chemical pregnancy? I had my period August 8th and got a positive pregnancy test September 4th. This week Monday September 10th I began to bleed and cramp. On September 11th I went in and my hcg was at a 11.1 and went back today and I’m at a 2.6. How long did it take you to conceive after your miscarriage or chemical pregnancy?
